https://en.wikipedia.org/wiki/Exeter%20Mathematics%20School | Exeter Mathematics School is a maths school located in Exeter in the English county of Devon.
It opened in September 2014 under the free schools initiative and is sponsored by Exeter College and the University of Exeter. It is intended to be a regional centre of excellence in mathematics for Cornwall, Devon, Dorset and Somerset. As a result, the school offers boarding facilities for pupils who live more than an hours drive away from the school. A total of 120 students are catered for at the school with some boarding from Monday to Friday during term time.
The school is highly selective, with prospective students expected to have GCSE qualifications at grade 8-9 in Mathematics and Physics or Computer Science. Prospective students must also have five GCSEs in total at grade 5 or above including English at grade 6. The course structure of Exeter Mathematics School requires all students to study A-level Mathematics and Further Mathematics and either A-level Physics or Computer Science. Students may choose to study both, but one may be chosen and an additional A-level from a wider range of options, which are taught at Exeter College, may be taken as an alternative.

https://en.wikipedia.org/wiki/Order%20polynomial | The order polynomial is a polynomial studied in mathematics, in particular in algebraic graph theory and algebraic combinatorics. The order polynomial counts the number of order-preserving maps from a poset to a chain of length . These order-preserving maps were first introduced by Richard P. Stanley while studying ordered structures and partitions as a Ph.D. student at Harvard University in 1971 under the guidance of Gian-Carlo Rota.
Definition
Let be a finite poset with elements denoted , and let be a chain elements. A map is order-preserving if implies . The number of such maps grows polynomially with , and the function that counts their number is the order polynomial .
Similarly, we can define an order polynomial that counts the number of strictly order-preserving maps , meaning implies . The number of such maps is the strict order polynomial .
Both and have degree . The order-preserving maps generalize the linear extensions of , the order-preserving bijections . In fact, the leading coefficient of and is the number of linear extensions divided by .
Examples
Letting be a chain of elements, we have and There is only one linear extension (the identity mapping), and both polynomials have leading term .
Letting be an antichain of incomparable elements, we have . Since any bijection is (strictly) order-preserving, there are linear extensions, and both polynomials reduce to the leading term .
Reciprocity theorem
There is a relation between strictly order-preserving maps and order-preserving maps:
In the case that is a chain, this recovers the negative binomial identity. There are similar results for the chromatic polynomial and Ehrhart polynomial (see below), all special cases of Stanley's general Reciprocity Theorem.
Connections with other counting polynomials
Chromatic polynomial
The chromatic polynomial counts the number of proper colorings of a finite graph with available colors. For an acyclic orientation of the edges of , there is a natural "downstream" partial order on the vertices implied by the basic relations whenever is a directed edge of . (Thus, the Hasse diagram of the poset is a subgraph of the oriented graph .) We say is compatible with if is order-preserving. Then we have
where runs over all acyclic orientations of G, considered as poset structures.
Order polytope and Ehrhart polynomial
The order polytope associates a polytope with a partial order. For a poset with elements, the order polytope is the set of order-preserving maps , where is the ordered unit interval, a continuous chain poset. More geometrically, we may list the elements , and identify any mapping with the point ; then the order polytope is the set of points with if .
The Ehrhart polynomial counts the number of integer lattice points inside the dilations of a polytope. Specifically, consider the lattice and a -dimensional polytope with vertices in ; then we define
the number of lattice points in , |
https://en.wikipedia.org/wiki/Wild%20problem | In the mathematical areas of linear algebra and representation theory, a problem is wild if it contains the problem of classifying pairs of square matrices up to simultaneous similarity. Examples of wild problems are classifying indecomposable representations of any quiver that is neither a Dynkin quiver (i.e. the underlying undirected graph of the quiver is a (finite) Dynkin diagram) nor a Euclidean quiver (i.e., the underlying undirected graph of the quiver is an affine Dynkin diagram).
Necessary and sufficient conditions have been proposed to check the simultaneously block triangularization and diagonalization of a finite set of matrices under the assumption that each matrix is diagonalizable over the field of the complex numbers.

https://en.wikipedia.org/wiki/Bibhutibhushan%20Datta | Bibhutibhushan Datta (also Bibhuti Bhusan Datta; Bengali : বিভূতিভূষণ দত্ত, Bibhūtibhūṣaṇ Datta) (28 June 1888 – 6 October 1958) was a historian of Indian mathematics.
Datta came from a poor Bengali family. He was a student of Ganesh Prasad, studied at University of Calcutta and secured the master's degree in mathematics in 1914 and doctorate degree in 1920 in applied mathematics. He taught at Calcutta University where he was lecturer at University Science College, and from 1924 to 1929 he was Rhashbehari Ghosh Professor of Applied Mathematics. During the 1920s and 1930s he created a reputation as an authority on the history of Indian mathematics. He was also deeply interested in Indian philosophy and religion. In 1929 he retired from his professorship and left the university in 1933, and became a sannyasin (an ascetic, a person who has renounced worldly pleasures) in 1938 under the name Swami Vidyaranya.
History of Hindu Mathematics: A Source Book, written by him jointly with Avadhesh Narayan Singh (1901–1954) became a standard reference in the history of Indian mathematics. He also wrote a monograph on the Shulba Sutras. He published more than 70 research papers mostly related to history of Indian mathematics.
In the last years of his life, as Swami Vidyaranya, he lived mainly at Pushkar (in Rajasthan).

https://en.wikipedia.org/wiki/Constant-recursive%20sequence | In mathematics and theoretical computer science, a constant-recursive sequence is an infinite sequence of numbers in which each number in the sequence is equal to a fixed linear combination of one or more of its immediate predecessors. The concept is variously known as a linear recurrence sequence, linear-recursive sequence, linear-recurrent sequence, a C-finite sequence, or a solution to a linear recurrence with constant coefficients.
A prototypical example is the Fibonacci sequence , in which each number is the sum of the previous two. The power of two sequence is also constant-recursive because each number is the sum of twice the previous number. The square number sequence is also constant-recursive. However, not all sequences are constant-recursive; for example, the factorial sequence is not constant-recursive. All arithmetic progressions, all geometric progressions, and all polynomials are constant-recursive.
Formally, a sequence of numbers is constant-recursive if it satisfies a recurrence relation
where are constants. For example, the Fibonacci sequence satisfies the recurrence relation where is the th Fibonacci number.
Constant-recursive sequences are studied in combinatorics and the theory of finite differences. They also arise in algebraic number theory, due to the relation of the sequence to polynomial roots; in the analysis of algorithms, as the running time of simple recursive functions; and in the theory of formal languages, where they count strings up to a given length in a regular language. Constant-recursive sequences are closed under important mathematical operations such as term-wise addition, term-wise multiplication, and Cauchy product.
The Skolem–Mahler–Lech theorem states that the zeros of a constant-recursive sequence have a regularly repeating (eventually periodic) form. On the other hand, the Skolem problem, which asks for an algorithm to determine whether a linear recurrence has at least one zero, remains unsolved.
Definition
A constant-recursive sequence is any sequence of integers, rational numbers, algebraic numbers, real numbers, or complex numbers (written as as a shorthand) satisfying a formula of the form
for all where are constants.
(This equation is called a linear recurrence with constant coefficients of order d.)
The order of the constant-recursive sequence is the smallest such that the sequence satisfies a formula of the above form, or for the everywhere-zero sequence.
The d coefficients must be coefficients ranging over the same domain as the sequence (integers, rational numbers, algebraic numbers, real numbers, or complex numbers). For example for a rational constant-recursive sequence, and must be rational numbers.
The definition above allows eventually-periodic sequences such as and . Some authors require that , which excludes such sequences.
Examples
Fibonacci and Lucas sequences
The sequence 0, 1, 1, 2, 3, 5, 8, 13, ... of Fibonacci numbers is constant-recursive of order 2 |

https://en.wikipedia.org/wiki/Raymond%20Ogden | Raymond William Ogden (born 19 September 1943) is a British applied mathematician. He is the George Sinclair Professor of Mathematics at the Department of Mathematics and Statistics of the University of Glasgow.
Education
Ogden earned his BA and PhD degrees from the University of Cambridge in 1970, under the supervision of Rodney Hill. His thesis was entitled On Constitutive Relations for Elastic and Plastic Materials.
Work
Ogden's research has been focused on the nonlinear theory of elasticity and its applications. His theoretical contributions include the derivation of exact solutions of nonlinear boundary value problems, for both compressible and incompressible materials, and an analysis of the linear and nonlinear stability of pre-stressed bodies and related studies of elastic wave propagation.
In the field of applications, Ogden worked on modelling the elastic and inelastic behaviour of rubber-like solids. He has also made contributions to the biomechanics of soft biological tissues, the electroelasticity and magnetoelasticity of electromechanically sensitive elastomeric materials, and the effects on residual stress in materials that are capable of large elastic deformations.
His book, Non-Linear Elastic Deformations, published in 1984 and reissued in 1999, has become a standard reference in this branch of solid mechanics.
Awards and honours
Ogden was awarded the ASME Koiter Medal in 2005 and the Prager Medal of the Society of Engineering Science in 2010. He was elected a Fellow of the Royal Society (FRS) in 2006.
In 2016, the American Society of Mechanical Engineers (ASME) awarded Ogden the Timoshenko Medal.

https://en.wikipedia.org/wiki/Segre%27s%20theorem | In projective geometry, Segre's theorem, named after the Italian mathematician Beniamino Segre, is the statement:
Any oval in a finite pappian projective plane of odd order is a nondegenerate projective conic section.
This statement was assumed 1949 by the two Finnish mathematicians G. Järnefelt and P. Kustaanheimo and its proof was published in 1955 by B. Segre.
A finite pappian projective plane can be imagined as the projective closure of the real plane (by a line at infinity), where the real numbers are replaced by a finite field . Odd order means that is odd. An oval is a curve similar to a circle (see definition below): any line meets it in at most 2 points and through any point of it there is exactly one tangent. The standard examples are the nondegenerate projective conic sections.
In pappian projective planes of even order greater than four there are ovals which are not conics. In an infinite plane there exist ovals, which are not conics. In the real plane one just glues a half of a circle and a suitable ellipse smoothly.
The proof of Segre's theorem, shown below, uses the 3-point version of Pascal's theorem and a property of a finite field of odd order, namely, that the product of all the nonzero elements equals -1.
Definition of an oval
In a projective plane a set of points is called oval, if:
(1) Any line meets in at most two points.
If the line is an exterior (or passing) line; in case a tangent line and if the line is a secant line.
(2) For any point there exists exactly one tangent at , i.e., .
For finite planes (i.e. the set of points is finite) we have a more convenient characterization:
For a finite projective plane of order (i.e. any line contains points) a set of points is an oval if and only if and no three points are collinear (on a common line).
Pascal's 3-point version
Theorem
Let be an oval in a pappian projective plane of characteristic .
is a nondegenerate conic if and only if statement (P3)
holds:
(P3): Let be any triangle on and the tangent at point to , then the points
are collinear.
Proof
Let the projective plane be coordinatized inhomogeneously over a field
such that is the tangent at , the x-axis is the tangent at the point and contains the point . Furthermore, we set (s. image)
The oval can be described by a function such that:
The tangent at point will be described using a function such that its equation is
Hence (s. image)
and
I: if is a non degenerate conic we have and and one calculates easily that are collinear.
II: If is an oval with property (P3), the slope of the line is equal to the slope of the line , that means:
and hence
(i): for all .
With one gets
(ii): and from we get
(iii):
(i) and (ii) yield
(iv): and with (iii) at least we get
(v): for all .
A consequence of (ii) and (v) is
.
Hence is a nondegenerate conic.
Remark:
Property (P3) is fulfilled for any oval in a pappian projective plane of characteristic 2 with a n |

https://en.wikipedia.org/wiki/List%20of%20NUTS%20regions%20in%20the%20European%20Union%20by%20GDP | This is a list of NUTS regions in the European Union by GDP. The European Union uses a classification for subnational territory called Nomenclature of Territorial Units for Statistics () (commonly abbreviated as NUTS). The NUTS 1 classification is applied to a group of regions, NUTS 2 for regions and NUTS 3 as subdivisions of regions. There are also two levels (NUTS 4 and 5) which relate to local administrative unit levels. Countries agree a NUTS classification with the European Commission. Geddes notes that NUTS level 2 is "particularly important", because they often exist as territorial-government divisions and are used for regional policies by countries. NUTS 1 typically has a population of 3-7 million; NUTS 2 0.8-3 million; and NUTS 3 150,000-800,000. As of 2015, there are 98 regions at NUTS 1 level, 276 regions at NUTS 2 level and 1,342 regions at NUTS 3 level (as a result, statistics at the NUTS level 3 are found as an external link to this article). The EU is based on the classification of NUTS 2 regions as: less developed regions, transition regions and more developed regions.
The EU's Structural Funds and Cohesion Fund direct funding to NUTS level 2 regions based on their GDP (PPS) per capita in comparison to the EU average: less developed regions (less than 75%), transition regions (between 75% and 90% and more developed regions (over 90%). For the period 2014–20, EUR 351 billion will be invested in the EU's regions with most being directed to the less developed regions.

https://en.wikipedia.org/wiki/Kenneth%20Walters | Kenneth Walters (1934 – 28 March 2022) was a British mathematician and rheologist. He was a Distinguished Research Professor at the Institute Of Mathematics, Physics and Computer Science of the Aberystwyth University.
Education
Walters earned his PhD from the University of Swansea in 1959 under the supervision of James G. Oldroyd. His thesis was entitled Some Elastico-Viscous Liquids with Continuous and Discrete Relaxation Spectra.
Work
Walters made contributions to rheology and the development of rheological science in the United Kingdom, and has conducted extensive studies of the behaviour of non-Newtonian fluids, particularly elastic liquids. He made advances in two major areas: the measurement of rheological properties, and the numerical solution of complex flows. In the first area, he extended the theory of viscometric flows, carried out a searching analysis of sources of error in the principal instruments in current use, and was involved in industrial applications arising in the manufacture of lubricants, detergents and paints. His book, Rheometry, is a standard work of reference and the book Numerical Simulation of Non-Newtonian Flow, of which he is joint author, is an influential text in this field of research.
Awards and honours
Prof. Walters was recognized extensively for his contributions to the rheological community by being awarded the Gold Medal from the British Society of Rheology in 1984 and the Weissenberg Award from the European Society of Rheology in 2002. Walters was elected a Fellow of the Royal Society (FRS) in 1991. In 1995 he was made a Foreign Associate of the National Academy of Engineering. He was an active member of the rheological community for many years. He served as President of the British Society of Rheology from 1974 to 1976, President of the European Society of Rheology from 1996 to 2000, and the Chairman of the International Committee on Rheology from 2000 to 2004.
Personal life
In 1961, Kenneth began dating Mary Eccles, an Aberystwyth student who had been Student ‘Rag Queen’ before they met. They were both committed Christians and married in 1963. Their mutual faith led them into lay leadership at St Michael's Anglican church in Aberystwyth. They had three children and seven grandchildren.
Death
Walters' death was announced on 30 March 2022.

https://en.wikipedia.org/wiki/Bronshtein%20and%20Semendyayev | Bronshtein and Semendyayev (often just Bronshtein or Bronstein, sometimes BS) is the informal name of a comprehensive handbook of fundamental working knowledge of mathematics and table of formulas originally compiled by the Russian mathematician Ilya Nikolaevich Bronshtein and engineer Konstantin Adolfovic Semendyayev.
The work was first published in 1945 in Russia and soon became a "standard" and frequently used guide for scientists, engineers, and technical university students. Over the decades, high popularity and a string of translations, extensions, re-translations and major revisions by various editors led to a complex international publishing history centered around the significantly expanded German version. Legal hurdles following the fall of the Iron Curtain caused the development to split into several independent branches maintained by different publishers and editors to the effect that there are now two considerably different publications associated with the original title – and both of them are available in several languages.
With some slight variations, the English version of the book was originally named A Guide-Book to Mathematics, but changed its name to Handbook of Mathematics. This name is still maintained up to the present by one of the branches. The other line is meanwhile named Users' Guide to Mathematics to help avoid confusion.
Overview
Bronshtein and Semendyayev is a comprehensive handbook of fundamental working knowledge of mathematics and table of formulas based on the Russian book (, literally: "Handbook of mathematics for engineers and students of technical universities") compiled by the Russian mathematician Ilya Nikolaevich Bronshtein () and engineer Konstantin Adolfovic Semendyayev ().
The scope is the concise discussion of all major fields of applied mathematics by definitions, tables and examples with a focus on practicability and with limited formal rigour. The work also contains a comprehensive list of analytically solvable integrals, that is, those integrals which can be described in closed form with antiderivatives.
History
With Dmitrii Abramovich Raikov, Bronshtein authored a Russian handbook on elementary mathematics, mechanics and physics (), which was published in 1943.
Around the same time in 1939/1940, Bronshtein, together with Semendyayev, also wrote their Russian handbook of mathematics for engineers and students of technical universities. Among other sources this work was influenced by the 1936 Russian translation of the 1931 edition of the much older German .
Hot lead typesetting had already started when the Siege of Leningrad prohibited further development and the print matrices were relocated. After the war, they were considered lost, but could be found again years later, so that the first edition of could finally be published in 1945.
The expanded German translation (literally: "Pocketbook of mathematics") by Viktor Ziegler was first published in 1958 by B. G. Teubner in Leipzig. It w |
https://en.wikipedia.org/wiki/Conservative%20functor | In category theory, a branch of mathematics, a conservative functor is a functor such that for any morphism f in C, F(f) being an isomorphism implies that f is an isomorphism.
Examples
The forgetful functors in algebra, such as from Grp to Set, are conservative. More generally, every monadic functor is conservative. In contrast, the forgetful functor from Top to Set is not conservative because not every continuous bijection is a homeomorphism.
Every faithful functor from a balanced category is conservative.

While at Brookhaven National Laboratory (1954-1987), he designed the logic for the MERLIN digital computer in 1958,
and served as chairman of the Applied Mathematics Department from 1964 to 1975.
Shimamoto researched in combinatorial mathematics, the economics of outer continental shelf oil and gas lease sales (on behalf of the U.S. Geological Survey), the architecture of supercomputers, and the linking of computers for parallel processing.
During the 1970s, he worked with Heinrich Heesch and Karl Durre on methods for a computer-aided proof of the four color theorem, using computer programs to apply Heesch's notion of "discharging" to eliminate 4-colorable cases.
A proof of the Four Color Theorem, which he presented in 1971, was later shown to be flawed, but it served as the basis for further work.
Born in Hawaii in 1924, Shimamoto served with the U.S. Army Signal Corps and Strategic Bombing Survey in Japan, during World War II. He died in New Jersey on August 27, 2009.

https://en.wikipedia.org/wiki/Prior-free%20mechanism | A prior-free mechanism (PFM) is a mechanism in which the designer does not have any information on the agents' valuations, not even that they are random variables from some unknown probability distribution.
A typical application is a seller who wants to sell some items to potential buyers. The seller wants to price the items in a way that will maximize his profit. The optimal prices depend on the amount that each buyer is willing to pay for each item. The seller does not know these amounts, and cannot even assume that the amounts are drawn from a probability distribution. The seller's goal is to design an auction that will produce a reasonable profit even in worst-case scenarios.
PFMs should be contrasted with two other mechanism types:
Bayesian-optimal mechanisms (BOM) assume that the agents' valuations are drawn from a known probability distribution. The mechanism is tailored to the parameters of this distribution (e.g., its median or mean value).
Prior-independent mechanisms (PIM) assume that the agents' valuations are drawn from an unknown probability distribution. They sample from this distribution in order to estimate the distribution parameters.
From the point-of-view of the designer, BOM is the easiest, then PIM, then PFM. The approximation guarantees of BOM and PIM are in expectation, while those of PFM are in worst-case.
What can we do without a prior? A naive approach is to use statistics: ask the potential buyers what their valuations are and use their replies to calculate an empirical distribution function. Then, apply the methods of Bayesian-optimal mechanism design to the empirical distribution function.
The problem with this naive approach is that the buyers may behave strategically. Since the buyers' answers affect the prices that they are going to pay, they may be incentivized to report false valuations in order to push the price down. The challenge in PFMD is to design truthful mechanisms. In truthful mechanisms, the agents cannot affect the prices they pay, so they have no incentive to report untruthfully.
Several approaches for designing truthful prior-free mechanisms are described below.
Deterministic empirical distribution
For every agent , let be the empirical distribution function calculated based on the valuations of all agents except . Use the Bayesian-optimal mechanism with to calculate price and allocation for agent .
Obviously, the bid of agent affects only the prices paid by other agents and not his own price; therefore, the mechanism is truthful.
This "empirical Myerson mechanism" works in some cases but not in others.
Here is a case in which it works quite well. Suppose we are in a digital goods auction. We ask the buyers for their valuation of the good, and get the following replies:
51 buyers bid "$1"
50 buyers bid "$3".
For each of the buyers in group 1, the empirical distribution is 50 $1-buyers and 50 $3-buyers, so the empirical distribution function is "0.5 chance of $1 and 0.5 chance of $3 |

The classical model scores expert performance in terms of statistical accuracy (sometimes called calibration) and informativeness
.
These terms should not be confused with “accuracy and precision”. Accuracy “is a description of systematic errors” while precision “is a description of random errors”. In the classical model statistical accuracy is measured as the p-value or probability with which one would falsely reject the hypotheses that an expert's probability assessments were statistically accurate. A low value (near zero) means it is very unlikely that the discrepancy between an expert's probability statements and observed outcomes should arise by chance. Informativeness is measured as Shannon relative information (or Kullback Leibler divergence) with respect to an analyst-supplied background measure. Shannon relative information is used because it is scale invariant, tail insensitive, slow, and familiar. Parenthetically, measures with physical dimensions, such as the standard deviation, or the width of prediction intervals, raise serious problems, as a change of units (meters to kilometers) would affect some variables but not others. The product of statistical accuracy and informativeness for each expert is their combined score. With an optimal choice of a statistical accuracy threshold beneath which experts are unweighted, the combined score is a long run “strictly proper scoring rule”: an expert achieves his long run maximal expected score by and only by stating his true beliefs. The classical model derives Performance Weighted (PW) combinations. These are compared with Equally Weighted (EW) combinations, and recently with Harmonically Weighted (HW) combinations, as well as with individual expert assessments.

https://en.wikipedia.org/wiki/London%20Institute%20for%20Mathematical%20Sciences | The London Institute (officially the London Institute for Mathematical Sciences) is Britain’s only independent research centre in theoretical physics and mathematics. It was founded to be an alternative to universities, where scientists have to spend time on teaching and administrative duties. Instead, the Institute gives its researchers the freedom and support to devote themselves to research full-time.
History
In 2008, the Texan physicist Thomas Fink had the idea for creating an independent British institute for physics and maths. It was initially met with scepticism. The then head of Cambridge’s Cavendish Laboratory, Peter Littlewood, told him, “An institute cannot live on grants alone.” But Caltech's Tom Tombrello, who had mentored Fink on his Physics 11 course, encouraged the idea. The Institute was founded in 2011 and received its first grant, from DARPA, the following year.
In 2015 it became eligible for funding from the EU scientific research agency. In 2019 it was awarded Independent Research Organisation status by UKRI, becoming the first independent research centre in the physical sciences to be allowed to compete with universities for funding from the seven Research Councils. In 2021 its researchers moved into the Royal Institution, occupying rooms that were once the private apartments of Sir Humphry Davy, Michael Faraday and John Tyndall, among others.
After Russia invaded Ukraine in February 2022, the Institute created the Arnold and Landau Fellowships, named after the Ukrainian mathematician Vladimir Arnold and the Russian physicist Lev Landau. Consisting of ten three-year full-time positions, this is the biggest programme of its kind in the world.
Research
The London Institute does research in theoretical physics and mathematics. It does not have laboratories and does not conduct experiments. The Institute is committed to curiosity-driven, theoretical research as this has historically led to the most far-reaching breakthroughs, such as gravity and electromagnetism. In an article in The Times, it defined its work as “spotting the patterns within patterns”, which is a way to “unify seemingly disconnected fields” and open up new perspectives and subfields.
Research at the London Institute spans four themes: Mathematics that unifies; The elegant universe; Life, learning and emergence; and the Theory of human enterprise. Its researchers have published papers on statistical physics in Nature Reviews Physics; algebraic geometry in the Journal of High Energy Physics; graph theory in the European Journal of Combinatorics; and network theory in Physical Review Letters.
In 2021, the UK government announced the launch of Advanced Research and Invention Agency (ARIA), a new science agency designed to support projects that may create "a paradigm shift in science". As a roadmap for the new agency, the London Institute compiled a list of the 23 Mathematical Challenges of our time. Inspired by David Hilbert’s list of 23 challenges, 17 of w |
https://en.wikipedia.org/wiki/Qvist%27s%20theorem | In projective geometry, Qvist's theorem, named after the Finnish mathematician , is a statement on ovals in finite projective planes. Standard examples of ovals are non-degenerate (projective) conic sections. The theorem gives an answer to the question How many tangents to an oval can pass through a point in a finite projective plane? The answer depends essentially upon the order (number of points on a line −1) of the plane.
Definition of an oval
In a projective plane a set of points is called an oval, if:
Any line meets in at most two points, and
For any point there exists exactly one tangent line through , i.e., }.
When the line is an exterior line (or passant), if a tangent line and if the line is a secant line.
For finite planes (i.e. the set of points is finite) we have a more convenient characterization:
For a finite projective plane of order (i.e. any line contains points) a set of points is an oval if and only if and no three points are collinear (on a common line).
Statement and proof of Qvist's theorem
Qvist's theorem
Let be an oval in a finite projective plane of order .
(a) If is odd,
every point is incident with 0 or 2 tangents.
(b) If is even,
there exists a point , the nucleus or knot, such that, the set of tangents to oval is the pencil of all lines through .
Proof
(a) Let be the tangent to at point and let be the remaining points of this line. For each , the lines through partition into sets of cardinality 2 or 1 or 0. Since the number is even, for any point , there must exist at least one more tangent through that point. The total number of tangents is , hence, there are exactly two tangents through each , and one other. Thus, for any point not in oval , if is on any tangent to it is on exactly two tangents.
(b) Let be a secant, } and }. Because is odd, through any , there passes at least one tangent . The total number of tangents is . Hence, through any point for there is exactly one tangent. If is the point of intersection of two tangents, no secant can pass through . Because , the number of tangents, is also the number of lines through any point, any line through is a tangent.
Example in a pappian plane of even order
Using inhomogeneous coordinates over a field even, the set
},
the projective closure of the parabola , is an oval with the point as nucleus (see image), i.e., any line , with , is a tangent.
Definition and property of hyperovals
Any oval in a finite projective plane of even order has a nucleus .
The point set } is called a hyperoval or ()-arc. (A finite oval is an ()-arc.)
One easily checks the following essential property of a hyperoval:
For a hyperoval and a point the pointset } is an oval.
This property provides a simple means of constructing additional ovals from a given oval.
Example
For a projective plane over a finite field even and , the set
} is an oval (conic section) (see image),
} is a hyperoval and
} is another oval that is not a conic |
https://en.wikipedia.org/wiki/History%20of%20Hindu%20Mathematics | History of Hindu Mathematics: A Source Book is a treatise on the history of Indian mathematics authored by Bibhutibhushan Datta and Awadhesh Narayan Singh and originally published in two parts in 1930's. The book has since been reissued in one volume by Asia Publishing House in 1962. The treatise has been a standard reference for the history of Indian mathematics for many years.
History of the book
Bibhutibhushan Datta, the senior author of the book, delivered a lecture titled "Contribution of the Ancient Hindus to Mathematics" on 20 December 1927 to the Allahabad University Mathematical Association. This address was published in the Bulletin of the Allahabad University Mathematical Association in two papers totalling 60 pages in length. Datta expanded this paper and wrote the treatise History of Hindu Mathematics in three volumes. Datta retired from academic life in 1933 and became an itinerant ascetic. At the time of retirement, the manuscript of the three-volume work was entrusted to his junior colleague Awadhesh Narayan Singh. Singh published the first two of these volumes as a joint publication. The first volume titled History of Hindu Mathematics. A Source Book (Part 1: Numerical notation and arithmetic) was published in 1935 and the second volume titled History of Hindu Mathematics. A Source Book (Part 2: Algebra) was published in 1938. The planned third volume was never published.
Contents of the book
This is basically a source book. Under various topics are collected translations of Sanskrit texts as found in Hindu mathematical texts.
Part 1
Part 1 of the book is divided into chapters. Chapter 1 gives details of the various methods employed by the Hindus for denoting numbers. The chapter also contains details of the gradual evolution of the decimal place value notation in India. Chapter 2 deals with arithmetic in general and it contains the details of various methods for performing the arithmetical operations using a "board". The evolution of the operations of addition, subtraction, multiplication, division, squaring, cubing, and the extraction square root and cube root are all discussed in detail.
Part 2
The whole of Part 2, running to about 307 pages, constitutes just one chapter numbered as Chapter 3 of the book. Some of the topics discussed in this chapter are linear equations with one unknown and with two unknowns, quadratic equations, linear indeterminate equations, solutions of equations of the form Nx2 + 1 = y2, indeterminate equations of higher degrees, and rational triangles.
From reviews
Reactions to the publication of the book were mixed: some were highly favorable and some were highly critical. For example, the reviewer in American Mathematical Monthly found the book "From the standpoint of authoritative subject matter and from that of book-making, it is a notable history", whereas the reviewer in Isis, a journal of the History of Science Society, found the book " . . . a mathematical panegyric on Hindu history.

https://en.wikipedia.org/wiki/Extended%20Mathematical%20Programming | Algebraic modeling languages like AIMMS, AMPL, GAMS, MPL and others have been developed to facilitate the description of a problem in mathematical terms and to link the abstract formulation with data-management systems on the one hand and appropriate algorithms for solution on the other. Robust algorithms and modeling language interfaces have been developed for a large variety of mathematical programming problems such as linear programs (LPs), nonlinear programs (NPs), Mixed Integer Programs (MIPs), mixed complementarity programs (MCPs) and others. Researchers are constantly updating the types of problems and algorithms that they wish to use to model in specific domain applications.
Extended Mathematical Programming (EMP) is an extension to algebraic modeling languages that facilitates the automatic reformulation of new model types by converting the EMP model into established mathematical programming classes to solve by mature solver algorithms. A number of important problem classes can be solved. Specific examples are variational inequalities, Nash equilibria, disjunctive programs and stochastic programs.
EMP is independent of the modeling language used but currently it is implemented only in GAMS. The new types of problems modeled with EMP are reformulated with the GAMS solver JAMS to well established types of problems and the reformulated models are passed to a suitable GAMS solver to be solved. The core of EMP is a file called where the annotations that are needed for the reformulations are added to the model.
Equilibrium problems
Equilibrium problems model questions arising in the study of economic equilibria in a mathematically abstract form. Equilibrium problems include Variational Inequalities, problems with Nash Equilibria, and Multiple Optimization Problems with Equilibrium Constraints (MOPECs). Use EMP's keywords to reformulate these problems as mixed complementarity problems (MCPs), a class of problems for which mature solver technology exists. Solve the newly reformulated EMP keyword version of the problem with the PATH solver or other GAMS MCP solvers.
Examples of the use of EMP to solve equilibrium problems include the computation of Cournot–Nash–Walras equilibria.., modeling water allocation, long-term planning of transmission line expansion of the electrical grid, modeling risk-averse agents in hydro-thermal electricity markets with uncertain inflows into hydro reservoirs and modeling variational inequalities in energy markets
Hierarchical optimization
Hierarchical optimization problems are mathematical programs with an additional optimization problem in their constraints. A simple example is the bilevel programming problem that optimizes an upper level objective over constraints that include another lower level optimization problem. Bilevel programming is used in many areas. One example is the design of optimal tax instruments. The tax instrument is modeled in the upper level and the clearing market is modeled in |

https://en.wikipedia.org/wiki/Sum%20of%20squares%20function | In number theory, the sum of squares function is an arithmetic function that gives the number of representations for a given positive integer as the sum of squares, where representations that differ only in the order of the summands or in the signs of the numbers being squared are counted as different, and is denoted by .
Definition
The function is defined as
where denotes the cardinality of a set. In other words, is the number of ways can be written as a sum of squares.
For example, since where each sum has two sign combinations, and also since with four sign combinations. On the other hand, because there is no way to represent 3 as a sum of two squares.
Formulae
k = 2
The number of ways to write a natural number as sum of two squares is given by . It is given explicitly by
where is the number of divisors of which are congruent to 1 modulo 4 and is the number of divisors of which are congruent to 3 modulo 4. Using sums, the expression can be written as:
The prime factorization , where are the prime factors of the form and are the prime factors of the form gives another formula
, if all exponents are even. If one or more are odd, then .
k = 3
Gauss proved that for a squarefree number ,
where denotes the class number of an integer .
There exist extensions of Gauss' formula to arbitrary integer .
k = 4
The number of ways to represent as the sum of four squares was due to Carl Gustav Jakob Jacobi and it is eight times the sum of all its divisors which are not divisible by 4, i.e.
Representing , where m is an odd integer, one can express in terms of the divisor function as follows:
k = 6
The number of ways to represent as the sum of six squares is given by
where is the Kronecker symbol.
k = 8
Jacobi also found an explicit formula for the case :

https://en.wikipedia.org/wiki/3x%20%2B%201%20semigroup | In algebra, the 3x + 1 semigroup is a special subsemigroup of the multiplicative semigroup of all positive rational numbers. The elements of a generating set of this semigroup are related to the sequence of numbers involved in the still open Collatz conjecture or the "3x + 1 problem". The 3x + 1 semigroup has been used to prove a weaker form of the Collatz conjecture. In fact, it was in such context the concept of the 3x + 1 semigroup was introduced by H. Farkas in 2005. Various generalizations of the 3x + 1 semigroup have been constructed and their properties have been investigated.
Definition
The 3x + 1 semigroup is the multiplicative semigroup of positive rational numbers generated by the set
The function T : Z → Z, where Z is the set of all integers, as defined below is used in the "shortcut" definition of the Collatz conjecture:
The Collatz conjecture asserts that for each positive integer n, there is some iterate of T with itself which maps n to 1, that is, there is some integer k such that T(k)(n) = 1. For example if n = 7 then the values of T(k)(n) for k = 1, 2, 3,... are 11, 17, 26, 13, 20, 10, 5, 8, 4, 2, 1 and T(11)(7) = 1.
The relation between the 3x + 1 semigroup and the Collatz conjecture is that the 3x + 1 semigroup is also generated by the set
The weak Collatz conjecture
The weak Collatz conjecture asserts the following: "The 3x + 1 semigroup contains every positive integer." This was formulated by Farkas and it has been proved to be true as a consequence of the following property of the 3x + 1 semigroup:
The 3x + 1 semigroup S equals the set of all positive rationals in lowest terms having the property that b ≠ 0 (mod 3). In particular, S contains every positive integer.
The wild semigroup
The semigroup generated by the set
which is also generated by the set
is called the wild semigroup. The integers in the wild semigroup consists of all integers m such that m ≠ 0 (mod 3).

The survey gathers information on Americans who died in a given year from their death certificates and family members (or others who are familiar with the decedent's life history.) The first NMFS was conducted in 1961, and focused on, among other topics, institutional and hospital care people received in the last year of their life. Subsequent surveys were conducted in 1962-3, 1964-5, 1966-8, 1986, and 1993. As of 2009, it is conducted by the National Vital Statistics System.

Pearcy was born in Beaumont, Texas and raised in Galveston, Texas and educated at Texas A&M University, the University of Chicago, and Rice University. His Ph. D. was taken from Rice University in 1960 under Arlen Brown. In 1963 Pearcy became a Hildebrandt Instructor at the University of Michigan. He was promoted to Professor in 1968 and remained there until 1990, when he retired and was named Professor of Mathematics at Texas A and M University.
Pearcy retired from that position in 2012.

https://en.wikipedia.org/wiki/Olive%20Jean%20Dunn | Olive Jean Dunn (1 September 1915 – 12 January 2008) was an American mathematician and statistician, and professor of biostatistics at the University of California Los Angeles (UCLA). She described methods for computing confidence intervals and also codified the Bonferroni correction's application to confidence intervals. She authored the textbook Basic Statistics: A Primer for the Biomedical Sciences in 1977.
Education and career
Dunn studied mathematics at the UCLA, earning a BA in 1936 and an MA in 1951. She was awarded a PhD in mathematics in 1956 at UCLA, supervised by Paul G. Hoel.
The title of Dunn's doctoral dissertation was Estimation problems for dependent regression.
In 1956, she was appointed assistant professor of statistics at Iowa State College. Dunn returned to UCLA in 1959 as assistant professor of biostatistics and assistant professor of preventive medicine and health, later becoming full professor and serving in that role until her retirement. Dunn served on the editorial boards of several journals.
Contributions to statistical methods and textbooks
Some of Dunn's 1958 and 1959 work led to the conjecture of the Gaussian correlation inequality, which was only proved by German mathematician Thomas Royen in 2014 and was only widely recognized as proved in 2017.
Dunn's doctoral dissertation work formed the basis for her continuing development of methods for confidence intervals in biostatistics, and the development of a method for correcting for multiple testing. From the notes to her 1959 publication on confidence intervals:"Most of the research for this paper was part of my doctoral dissertation. The idea of writing an article for the research worker who uses statistical methods was suggested to me by one of the non-statisticians on my doctoral committee at the time of my final examination. In working on the various confidence intervals for k means, I thought of the Bonferroni inequality ones quite early, but since they were so simple I thought they couldn't possibly be of any use. I spent a long time trying to prove that the confidence intervals which would be used in the case of independent variables could also be used or dependent variables. After failing to find a general proof for this, I finally noticed that the simple Bonferroni intervals were nearly as short."The first edition of her textbook, Basic statistics: a primer for the biomedical sciences, was published in 1964 Later editions were co-authored with another professor from UCLA, Virginia A. Clark. Dunn and Clark also co-authored Applied statistics: an analysis of variance and regression, which has also had several editions, with Ruth Mickey joining the authors.
Honors
Dunn became a Fellow of the American Statistical Association in 1968. She was also a fellow of the American Association for the Advancement of Science (AAAS) and the American Public Health Association.
In October 1974, Dunn was honored as the annual UCLA annual Woman of Science, awarded to " |

https://en.wikipedia.org/wiki/Oktisi | Oktisi (, ) is a village in the municipality of Struga, North Macedonia.
History
In 1900, Vasil Kanchov gathered and compiled statistics on demographics in the area and reported that the village of Oktisi was inhabited by about 840 Bulgarian Christians and 550 Bulgarian Muslims.
The "La Macédoine et sa Population Chrétienne" survey by Dimitar Mishev (D. Brankov) concluded that the Christian part of the local population in 1905 was composed of 1016 Bulgarian Exarchists. There was a Bulgarian school in the beginning of 20th century
Oktis Basilica
The Oktis Basilica was a paleochristian basilica in the northern part of the village of Oktis, but the church of the village (St. Nicholas) was built on the foundations of this basilica in 1927. In 1954, the Archaeological Museum of Macedonia undertook excavations of the basilica, which continued until 1994 under Dimçe Koço. The basilica has dimensions of 27.20 x 24.10 m., and consists of a narthex, exonarthex, side annexes and an intersection. It was constructed in a single phase. The floors of the central ship, the narthex, the crossroads, and the northern annex are filled with mosaics, decorated with geometric elements and fauna as well as a few preserved parts of the animal world. The Oktis Basilica is believed to originate in the 5th century as a sacred temple for the inhabitants of that early Christian period, which are hypothesised to be part of the wider ancestral population of the Albanians. The archaeological materials found in the excavations of the site are preserved in the People's Museum of Struga. It is possible that the mosaic in the narthex of the basilica represents the awareness of Christian unity among the early Albanian Byzantine Christian communities.
Demographics
Oktisi has traditionally been inhabited by Orthodox Macedonians and a Torbeš population.
As of the 2021 census, Oktisi had 1,925 residents with the following ethnic composition:

https://en.wikipedia.org/wiki/John%20Clayton%20Taylor | John Clayton Taylor (born 4 August 1930) is a British mathematical physicist. He is an Emeritus Professor of Mathematical Physics at the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge and an Emeritus Fellow of Robinson College. He is the father of mathematician Richard Taylor.
Education
Taylor earned his PhD from the University of Cambridge in 1956, under the supervision of Richard J. Eden and Abdus Salam. His thesis was entitled Renormalisation and Related Topics in Quantum Field Theory.
Research
Taylor has made contributions to quantum field theory and the physics of elementary particles. His contributions include: the discovery (also made independently by Lev Landau) of singularities in the analytical structure of the Feynman integrals for processes in quantum field theory, the PCAC nature of radioactive decay of the pion and the discovery in 1971 of the so-called Slavnov–Taylor identities, which control symmetry and renormalisation of gauge theories.
With various collaborators, in 1980 he discovered that real and virtual infrared divergences do not cancel in QCD as they do in QED. They also showed how these infrared divergences exponentiate. In addition, they contributed to the resummation programme in thermal QCD, simplifying the "hard" part of the effective action. Later, they studied complications arising from the non-polynomial nature of the QCD Hamiltonian in the (unitary) Coulomb gauge.

https://en.wikipedia.org/wiki/Antoine%20Cavalleri | Antoine Cavalleri (1698–1765) was a Jesuit professor of mathematics at Cahors during much of the French Enlightenment in the 18th century, until late in the reign of Louis XV of France.
Intellectual climate of the age
During the early years of the 18th century Isaac Newton's work on gravity was still incompletely accepted in France and Descartes' vortex theory had not yet been conclusively superseded. One result was the difficulty of formulating and establishing a coherent and compelling explanatory theory of tidal action. The French Académie Royale des Sciences both supported practical research into tidal effects, and offered a prize for the best essay to establish the topic on a sound mathematical and theoretical footing.
Three essays were selected for prizes, all of them by supporters of Newtonian theory. They were Daniel Bernoulli, Leonhard Euler, and Colin Maclaurin. However, it was rumoured by Pierre Louis Maupertuis that the reason that Cavalleri was added to the list of winners was that one influential judge among those selecting the winning essays was René Antoine Ferchault de Réaumur, who favoured Decartes' vortex theory, and who insisted that at least one winner should be a supporter of that view, though by that time it was rapidly losing ground and leading workers in the field already were rejecting it. As a sop for Réaumur, his colleagues consented to include an arbitrary choice of essay supporting the vorticist view. Cavalleri not only was fairly prominent in his own right, but had recently won two prizes from the Académie de Bordeaux for his essays: "Opacité et diaphanéité des corps" in 1738 and "Chaleur et froideur des eaux minérales" in 1739, so he was a convenient choice.
Cavalleri's obscurity
Though competent, Cavalleri is little remembered. He was perhaps doubly unfortunate; firstly, in an age that produced figures such as the Bernoulli family, Euler, Lacaille, D'Alembert, Reaumur, and Lagrange, even a prominent professor of mathematics is easy to overlook. Secondly, Cavalleri's essay on tides, though penetrating in that he recognised debatable points in both Cartesian and Newtonian theory, amounted to the last substantial support for the Cartesian theory of vortices; in effect a futile rearguard action. It is true that Fontenelle has been referred to as the last defender of the vortices, but unlike Cavalleri he wrote as an interpreter and populariser, rather than as an analyst or formulator of material theory.
On the one hand Cavalleri's objection to Descartes' theory was mainly that it effectively dismissed the obvious tidal influence of the sun. On the other he rejected Newton's theory of remote gravitational attraction. The latter idea might seem naive, but even in 21st century theoretical physics there are echoes of dissatisfaction with the concept of action at a distance. He tried to construct a theoretical basis for an inverse square law of gravitational attraction arising from Cartesian vortices. Newton however, h |

https://en.wikipedia.org/wiki/Moduli%20stack%20of%20elliptic%20curves | In mathematics, the moduli stack of elliptic curves, denoted as or , is an algebraic stack over classifying elliptic curves. Note that it is a special case of the moduli stack of algebraic curves . In particular its points with values in some field correspond to elliptic curves over the field, and more generally morphisms from a scheme to it correspond to elliptic curves over . The construction of this space spans over a century because of the various generalizations of elliptic curves as the field has developed. All of these generalizations are contained in .
Properties
Smooth Deligne-Mumford stack
The moduli stack of elliptic curves is a smooth separated Deligne–Mumford stack of finite type over , but is not a scheme as elliptic curves have non-trivial automorphisms.
j-invariant
There is a proper morphism of to the affine line, the coarse moduli space of elliptic curves, given by the j-invariant of an elliptic curve.
Construction over the complex numbers
It is a classical observation that every elliptic curve over is classified by its periods. Given a basis for its integral homology and a global holomorphic differential form (which exists since it is smooth and the dimension of the space of such differentials is equal to the genus, 1), the integralsgive the generators for a -lattice of rank 2 inside of pg 158. Conversely, given an integral lattice of rank inside of , there is an embedding of the complex torus into from the Weierstrass P function pg 165. This isomorphic correspondence is given byand holds up to homothety of the lattice , which is the equivalence relationIt is standard to then write the lattice in the form for , an element of the upper half-plane, since the lattice could be multiplied by , and both generate the same sublattice. Then, the upper half-plane gives a parameter space of all elliptic curves over . There is an additional equivalence of curves given by the action of thewhere an elliptic curve defined by the lattice is isomorphic to curves defined by the lattice given by the modular actionThen, the moduli stack of elliptic curves over is given by the stack quotientNote some authors construct this moduli space by instead using the action of the Modular group . In this case, the points in having only trivial stabilizers are dense.
Stacky/Orbifold points
Generically, the points in are isomorphic to the classifying stack since every elliptic curve corresponds to a double cover of , so the -action on the point corresponds to the involution of these two branches of the covering. There are a few special points pg 10-11 corresponding to elliptic curves with -invariant equal to and where the automorphism groups are of order 4, 6, respectively pg 170. One point in the Fundamental domain with stabilizer of order corresponds to , and the points corresponding to the stabilizer of order correspond to pg 78.

https://en.wikipedia.org/wiki/Cone%20condition | In mathematics, the cone condition is a property which may be satisfied by a subset of a Euclidean space. Informally, it requires that for each point in the subset a cone with vertex in that point must be contained in the subset itself, and so the subset is "non-flat".
Formal definitions
An open subset of a Euclidean space is said to satisfy the weak cone condition if, for all , the cone is contained in . Here represents a cone with vertex in the origin, constant opening, axis given by the vector , and height .

https://en.wikipedia.org/wiki/Worldly%20cardinal | In mathematical set theory, a worldly cardinal is a cardinal κ such that the rank Vκ is a model of Zermelo–Fraenkel set theory.
Relationship to inaccessible cardinals
By Zermelo's theorem on inaccessible cardinals, every inaccessible cardinal is worldly. By Shepherdson's theorem, inaccessibility is equivalent to the stronger statement that (Vκ, Vκ+1) is a model of second order Zermelo-Fraenkel set theory.
Being worldly and being inaccessible are not equivalent; in fact, the smallest worldly cardinal has countable cofinality and therefore is a singular cardinal.
The following are in strictly increasing order, where ι is the least inaccessible cardinal:
The least worldly κ.
The least worldly κ and λ (κ<λ, and same below) with Vκ and Vλ satisfying the same theory.
The least worldly κ that is a limit of worldly cardinals (equivalently, a limit of κ worldly cardinals).
The least worldly κ and λ with Vκ ≺Σ2 Vλ (this is higher than even a κ-fold iteration of the above item).
The least worldly κ and λ with Vκ ≺ Vλ.
The least worldly κ of cofinality ω1 (corresponds to the extension of the above item to a chain of length ω1).
The least worldly κ of cofinality ω2 (and so on).
The least κ>ω with Vκ satisfying replacement for the language augmented with the (Vκ,∈) satisfaction relation.
The least κ inaccessible in Lκ(Vκ); equivalently, the least κ>ω with Vκ satisfying replacement for formulas in Vκ in the infinitary logic L∞,ω.
The least κ with a transitive model M⊂Vκ+1 extending Vκ satisfying Morse–Kelley set theory.
(not a worldly cardinal) The least κ with Vκ having the same Σ2 theory as Vι.
The least κ with Vκ and Vι having the same theory.
The least κ with Lκ(Vκ) and Lι(Vι) having the same theory.
(not a worldly cardinal) The least κ with Vκ and Vι having the same Σ2 theory with real parameters.
(not a worldly cardinal) The least κ with Vκ ≺Σ2 Vι.
The least κ with Vκ ≺ Vι.
The least infinite κ with Vκ and Vι satisfying the same L∞,ω statements that are in Vκ.
The least κ with a transitive model M⊂Vκ+1 extending Vκ and satisfying the same sentences with parameters in Vκ as Vι+1 does.
The least inaccessible cardinal ι.

https://en.wikipedia.org/wiki/Quillen%20metric | In mathematics, and especially differential geometry, the Quillen metric is a metric on the determinant line bundle of a family of operators. It was introduced by Daniel Quillen for certain elliptic operators over a Riemann surface, and generalized to higher-dimensional manifolds by Jean-Michel Bismut and Dan Freed.
The Quillen metric was used by Quillen to give a differential-geometric interpretation of the ample line bundle over the moduli space of vector bundles on a compact Riemann surface, known as the Quillen determinant line bundle. It can be seen as defining the Chern–Weil representative of the first Chern class of this ample line bundle. The Quillen metric construction and its generalizations were used by Bismut and Freed to compute the holonomy of certain determinant line bundles of Dirac operators, and this holonomy is associated to certain anomaly cancellations in Chern–Simons theory predicted by Edward Witten.
The Quillen metric was also used by Simon Donaldson in 1987 in a new inductive proof of the Hitchin–Kobayashi correspondence for projective algebraic manifolds, published one year after the resolution of the correspondence by Shing-Tung Yau and Karen Uhlenbeck for arbitrary compact Kähler manifolds.
Determinant line bundle of a family of operators
Suppose are a family of Fredholm operators between Hilbert spaces, varying continuously with respect to for some topological space . Since each of these operators is Fredholm, the kernel and cokernel are finite-dimensional. Thus there are assignments
which define families of vector spaces over . Despite the assumption that the operators vary continuously in , these assignments of vector spaces do not form vector bundles over the topological space , because the dimension of the kernel and cokernel may jump discontinuously for a family of differential operators. However, the index of a differential operator, the dimension of the kernel subtracted by the dimension of the cokernel, is an invariant up to continuous deformations. That is, the assignment
is a constant function on . Since it is not possible to take a difference of vector bundles, it is not possible to combine the families of kernels and cokernels of into a vector bundle. However, in the K-theory of , formal differences of vector bundles may be taken, and associated to the family is an element
This virtual index bundle contains information about the analytical properties of the family , and its virtual rank, the difference of dimensions, may be computed using the Atiyah–Singer index theorem, provided the operators are elliptic differential operators.
Whilst the virtual index bundle is not a genuine vector bundle over the parameter space , it is possible to pass to a genuine line bundle constructed out of . For any , the determinant line of is defined as the one-dimensional vector space
One defines the determinant line bundle of the family as the fibrewise determinant of the virtual index bundle,

https://en.wikipedia.org/wiki/Continental%20Classroom | Continental Classroom is a U.S. educational television program that was broadcast on the NBC network five days a week in the early morning from 1958 to 1963, covering physics, chemistry, mathematics, and American government. It was targeted at teachers and college students and many institutions offered college credit for courses of which the broadcasts were the main component. The physics course was the first course in the subject available for credit nationwide and the government course was the first nationally broadcast TV course in social studies; the mathematics course has been called the first MOOC (massive open online course) in statistics.
Background, production and format
The idea for the course came from the drive to upgrade science education in the US after the Soviet Union's successful launch of Sputnik in 1957. Learning of a plan by the New York State Commissioner of Education, James Allen, to spend $600,000 on a refresher course for science teachers, Edward Stanley, Director of Public Affairs and Education at NBC, decided the network could do the same nationwide for not much more money. The American Association of Colleges for Teacher Education was also planning a pilot project on using television in teacher training. Major funding for the program came from the Ford Foundation and from various corporations. The title came from a phrase Stanley used to explain the idea to James Killian, science advisor to President Eisenhower. Physics for the nuclear age was the topic of the first year's course, which was broadcast from 6:30 to 7:00 in the morning Monday through Friday. The second course, in chemistry, was preceded by a rebroadcast of the physics course at 6:00 am. Courses in mathematics and American government followed. The Ford Foundation withdrew its funding for the fourth season, and the network subsequently canceled the program. The fifth season was a rebroadcast of the fourth, the last program airing on May 17, 1963.
Lecturers were paid $40,000 for a year of at least 130 half-hour lectures, and could have one or more paid assistants. They were given use of an apartment in Manhattan and their children were placed by NBC in good schools. They worked from outlines, rather than memorizing scripts. Each lecture was recorded in a four-hour studio session some two weeks ahead of the air date, usually in the afternoon by instructor preference. The first two seasons used three cameras; after the loss of the Ford Foundation support, this was reduced to two. The total budget was between $1.2 and $1.5 million a year.
The program attracted more viewers and a wider variety of viewers than NBC had expected: 400,000 for the physics course, 600,000 for chemistry, and one and a half million for American government, and including high-school classes (two of them for blind students), more than 800 engineers in the San Francisco Bay Area, nuns, 500 inmates of San Quentin State Prison in California, parents of students studying science, and other |
https://en.wikipedia.org/wiki/Fulton%20County%20Health%20Center | Fulton County Health Center (FCHC) is a rural critical access hospital. It serves the community of Fulton County, and is located in Wauseon Ohio.
Patient care statistics
U.S. News & World Report collates the number of patients seen by the hospital annually, as follows:
Facilities
Hospital
The FCHC facility is equipped as a general medical and surgery hospital, with the following special units:
Emergency department with 20 beds.
Helipad for medical evacuation.
Vascular diagnostic imaging and a heart catheterization system.
Wound care and hyperbaric oxygen therapy (HBOT).
Oncology treatment center.
Critical care unit.
Obstetrics and birthing center.
Sleep medicine.
Health center
The FCHC campus covers 28 acres. On the grounds are additional facilities that together comprise a complete health care center for the community. They include:
Fulton Manor and Fulton Suites, a nursing home.
FulCare Behavioral Health, a mental health facility.
Dialysis center operated by DaVita Inc.
Free Care Clinic at FCHC Medical Office Building.
Community
A fitness center is located within a rehabilitation facility in Wauseon's historic downtown business district, near the original Wauseon City Hospital.
The hospital's sleep lab has been expanded off-campus to Swanton, Ohio with two more beds, which doubles the capacity of FCHC's sleep medicine department.
History
FCHC has published a newsletter since 2009 named "Health Centering," which is mailed quarterly to residents in the community. PDF versions are available on the website, and these past issues contain a rich history of the hospital.
Early history
1903: Wauseon's first City Hospital was built originally as Wauseon High School in 1868. When the school moved, the building was converted and used as a hospital in 1903. The old hospital still stands today and houses the Fulton County Ohio Historical Society.
1930: Detwiler Memorial Hospital was built in 1929 and opened in 1930. After a new hospital was built across the road, the county then converted the hospital into a nursing home called Detwiler Manor. Later, the manor moved across the road to facilities on the current hospital campus. The beautiful historic brick building was renovated, once again re-purposed, and now houses the Fulton County's Job & Family Services offices.
Today's campus
The government of Fulton County, Ohio, owns the campus property.
1973: The current hospital facility opened in 1973, and was very progressive in design, featuring single-patient private rooms. Private rooms, while initially expensive to build, keep patients safer from hospital-acquired infections like MRSA.
While originally built a size large enough to house 106 beds, changing community needs has resulted in FCHC now having only a maximum 25 bed in-patient capacity, complying with federal Critical Access Hospital (CAH) guidelines. Many of the former patient rooms have been converted to other uses.
1996: The 1990s saw the former hospital acro |

https://en.wikipedia.org/wiki/Normal%20plane%20%28geometry%29 | A normal plane is any plane containing the normal vector of a surface at a particular point.
The normal plane also refers to the plane that is perpendicular to the tangent vector of a space curve; (this plane also contains the normal vector) see Frenet–Serret formulas.
Normal section
The normal section of a surface at a particular point is the curve produced by the intersection of that surface with a normal plane.
The curvature of the normal section is called the normal curvature.
If the surface is bow or cylinder shaped, the maximum and the minimum of these curvatures are the principal curvatures.
If the surface is saddle shaped the maxima of both sides are the principal curvatures.
The product of the principal curvatures is the Gaussian curvature of the surface (negative for saddle shaped surfaces).
The mean of the principal curvatures is the mean curvature of the surface; if (and only if) the mean curvature is zero, the surface is called a minimal surface.

https://en.wikipedia.org/wiki/Lorenzo%20Ramero | Lorenzo Ramero is an Italian mathematician living in France, specialized in algebraic and arithmetic geometry. He is currently a professor of mathematics at the University of Lille.
Ramero obtained his Laurea in Matematica from the University of Pisa and his Diploma from the Scuola Normale Superiore di Pisa in 1989. He completed his Ph.D. at the Massachusetts Institute of Technology in 1994 under the supervision of Alexander Beilinson, with a thesis titled An -adic Fourier transform over local fields.
Together with Ofer Gabber, Ramero developed the algebraic geometry based on almost rings extending earlier ideas of Gerd Faltings on "almost mathematics". This theory extends already classical algebraic geometry formalism of Alexander Grothendieck's school in order to treat new phenomena in p-adic Hodge theory. This work is systematized in their monograph Almost ring theory.
More foundational material was developed after the first book, and especially an extended theory of perfectoid rings and perfectoid spaces which generalizes the recent work of Peter Scholze. These aspects were recapitulated in the book "Foundations for Almost Ring Theory".

https://en.wikipedia.org/wiki/Suicide%20in%20Iran | Suicide in Iran is believed to be a growing concern in recent years. According to statistics most of the people who commit suicide are between the ages of 15 and 35.
Economic problems, mental illnesses, cultural obligations, political issues, and social pressures are the major factors for suicide commission in Iran.
Per Iranian Legal Medicine Organization statistics are classified to avoid negative atmosphere.
Definitions
The word "suicide" in Persian dictionaries like Moeen, Dehkhoda, and Amid, has been defined as "killing self by any means". The Oxford English Dictionary records the first use of the word "suicide" by Walter Charleton in 1651.
Apparently the word suicide in French was used by Pierre Desfontaines for the first time. Later, this word was accepted by the French Academy of Sciences. Ali EslamiNasab, considers the combination of two Latin words sui (self=) and cide (killing=Persian:کُشتن) a correct term for suicide (self-killing=Persian: خودکشی khudkushi). The concept of suicide in the Moaser Persian Dictionary is defined as "the intentional termination of life by one's own intention and own hands".
The first sociological analysis of suicide has been put forward by the French sociologist, Émile Durkheim. He states in his 1897 book suicide that "suicide is any type of death which is a direct or indirect cause of the victim's own positive or negative acts that he/she was aware of in advance". Durkheim categorized suicides into the following four types all of which are related to the relationship of the individual to society: 1- Egoistic suicide that is the cause of individualism and the separation from the society; 2- Altruistic suicide that occurs when the individual has a deep attachment to the society; 3- Anomic suicide which is the cause of anomie and lawlessness in the society; and 4- Fatalistic suicide that occurs when the wills, emotions and incentives of the members of the society is under the restrict control of the society.
In the late 19th century, Sigmund Freud was the first to review suicide from a psychological point of view. He considered suicide as "the ultimate anger towards self caused by the unconscious". Freud, divided human instincts into two categories: death instinct (Thanatos) and life instinct (Eros). He believed that the death instinct starts immediately after birth and intends to return in the future. This instinct is the cause of extinction, grudge, and termination of generation (reproduction). On the other hand, the life instinct is the cause of friendship, love, and reproduction. Gradually, Freud developed his theory of death instinct, which is in opposition to libido.
Erwin Stengel is the first person to differentiate between suicide and suicide intention from a psychological point of view. After some research, he dedicated an independent branch of psychology to the suicide intention. Research has suggested that unlike suicide the intention of suicide has other goals than just simple "self destruct |

https://en.wikipedia.org/wiki/Maryna%20Viazovska | Maryna Sergiivna Viazovska (, ; born 2 December 1984) is a Ukrainian mathematician known for her work in sphere packing. She is a full professor and Chair of Number Theory at the Institute of Mathematics of the École Polytechnique Fédérale de Lausanne in Switzerland. She was awarded the Fields Medal in 2022.
Education and career
Viazovska was born in Kyiv, the oldest of three sisters. Her father was a chemist who worked at the Antonov aircraft factory and her mother an engineer. She attended a specialized secondary school for high-achieving students in science and technology, Kyiv Natural Science Lyceum No. 145. An influential teacher there, Andrii Knyazyuk, had previously worked as a professional research mathematician before becoming a secondary school teacher. Viazovska competed in domestic mathematics Olympiads when she was at high school, placing 13th in a national competition where 12 students were selected to a training camp before a six-member team for the International Mathematical Olympiad was chosen. As a student at Taras Shevchenko National University of Kyiv, she competed at the International Mathematics Competition for University Students in 2002, 2003, 2004, and 2005, and was one of the first-place winners in 2002 and 2005. She co-authored her first research paper in 2005.
Viazovska earned a master's from the University of Kaiserslautern in 2007, PhD from the Institute of Mathematics of the National Academy of Sciences of Ukraine in 2010, and a doctorate (Dr. rer. nat.) from the University of Bonn in 2013. Her doctoral dissertation, Modular Functions and Special Cycles, concerns analytic number theory and was supervised by Don Zagier and Werner Müller.
She was a postdoctoral researcher at the Berlin Mathematical School and the Humboldt University of Berlin and a Minerva Distinguished Visitor at Princeton University. Since January 2018 she has held the Chair of Number Theory as a full professor at the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland after a short stint as tenure-track assistant professor.
Contributions
In 2016, Viazovska solved the sphere-packing problem in dimension 8. Her dimension 8 solution quickly led to collaboration with others, and a solution in dimension 24. Previously, the problem had been solved only for three or fewer dimensions, and the proof of the three-dimensional version (the Kepler conjecture) involved long computer calculations. In contrast, Viazovska's proof for 8 and 24 dimensions is "stunningly simple".
As well as for her work on sphere packing, Viazovska is also known for her research on spherical designs with Bondarenko and Radchenko. With them she proved a conjecture of Korevaar and Meyers on the existence of small designs in arbitrary dimensions. This result was one of the contributions for which her co-author Andriy Bondarenko won the Vasil A. Popov Prize for approximation theory in 2013.
Recognition
In 2016, Viazovska received the Salem Prize and, in 2017, the Clay Res |

https://en.wikipedia.org/wiki/Mary%20Wynne%20Warner | Mary Wynne Warner (née Davies; 22 June 1932 – 1 April 1998) was a Welsh mathematician, specializing in fuzzy mathematics. Her obituary in the Bulletin of the London Mathematical Society noted that fuzzy topology was "the field in which she was one of the pioneers and recognized as one of the leading figures for the past thirty years."
Early life and education
Mary Wynne Davies was born in Carmarthen, Wales, the elder daughter of Sydney and Esther Davies (née Jones), where the family resided until she was six years old. She was raised and received the first ten years of her education in Llandovery, where her father was a schoolmaster at the local grammar school. Attaining ten Distinctions in her School Certificate exams, she received the remainder of her secondary education at Howell's Boarding School, Denbigh in order to facilitate her study of physics.
Both a Draper's Company Exhibition and an Open Scholarship were awarded to Warner following academic distinction at Howell's. This facilitated her undergraduate study of mathematics at Somerville College, Oxford, commencing in 1951 and from which she graduated in 1953 with a second-class degree.
Warner had acquired various academic prizes at both the college and university level during her undergraduate degree, allowing her to progress to doctoral work in Oxford via a Research Scholarship. In 1956 her earliest research paper, 'A note on Borsuk's antipodal point theorem in the Oxford Quarterly Journal of Mathematics was published under the supervision of the Waynflete Chair of Pure Mathematics, J.H.C Whitehead. During this period, Warner was initiated into his notable and prolific algebraic topology research group.
Amid her academic study, Warner began a romantic relationship with Gerald Warner, who had read history at Oxford, and after graduating in 1954 had embarked upon a career in the Diplomatic Service's Intelligence Branch. She would marry Warner in 1956 before his assignment to Beijing, China. The transient nature of his occupation disrupted her ability to participate formally in academia and terminated her doctoral studies at Oxford, but she continued to dedicate herself to mathematical research to the extent that the demands of being a diplomat's wife would allow.
Career and legacy
The trajectory of Warner's career was shaped by her husband's overseas diplomatic assignments.
Whilst stationed in Beijing between 1956 and 1958 Warner continued her involvement with Oxford's Whitehead research group, working alongside prominent Chinese topologist Chang Su-chen until escalating political tensions forced them to terminate communication in 1958.
The family subsequently returned to London, England for a period between 1958 and 1960 during which Mary lectured part-time at Bedford College; this was followed by a year overseas in Rangoon, Burma. Under her instruction and direction as Senior Lecturer in Mathematics at Rangoon University, its first MSc Mathematics program was developed. Prior t |
