https://en.wikipedia.org/wiki/Intuitive%20statistics | Intuitive statistics, or folk statistics, is the cognitive phenomenon where organisms use data to make generalizations and predictions about the world. This can be a small amount of sample data or training instances, which in turn contribute to inductive inferences about either population-level properties, future data, or both. Inferences can involve revising hypotheses, or beliefs, in light of probabilistic data that inform and motivate future predictions. The informal tendency for cognitive animals to intuitively generate statistical inferences, when formalized with certain axioms of probability theory, constitutes statistics as an academic discipline.
Because this capacity can accommodate a broad range of informational domains, the subject matter is similarly broad and overlaps substantially with other cognitive phenomena. Indeed, some have argued that "cognition as an intuitive statistician" is an apt companion metaphor to the computer metaphor of cognition. Others appeal to a variety of statistical and probabilistic mechanisms behind theory construction and category structuring. Research in this domain commonly focuses on generalizations relating to number, relative frequency, risk, and any systematic signatures in inferential capacity that an organism (e.g., humans, or non-human primates) might have.
Background and theory
Intuitive inferences can involve generating hypotheses from incoming sense data, such as categorization and concept structuring. Data are typically probabilistic and uncertainty is the rule, rather than the exception, in learning, perception, language, and thought. Recently, researchers have drawn from ideas in probability theory, philosophy of mind, computer science, and psychology to model cognition as a predictive and generative system of probabilistic representations, allowing information structures to support multiple inferences in a variety of contexts and combinations. This approach has been called a probabilistic language of thought because it constructs representations probabilistically, from pre-existing concepts to predict a possible and likely state of the world.
Probability
Statisticians and probability theorists have long debated about the use of various tools, assumptions, and problems relating to inductive inference in particular. David Hume famously considered the problem of induction, questioning the logical foundations of how and why people can arrive at conclusions that extend beyond past experiences - both spatiotemporally and epistemologically. More recently, theorists have considered the problem by emphasizing techniques for arriving from data to hypothesis using formal content-independent procedures, or in contrast, by considering informal, content-dependent tools for inductive inference. Searches for formal procedures have led to different developments in statistical inference and probability theory with different assumptions, including Fisherian frequentist statistics, Bayesian inference, and |
https://en.wikipedia.org/wiki/Three-gap%20theorem | In mathematics, the three-gap theorem, three-distance theorem, or Steinhaus conjecture states that if one places points on a circle, at angles of , , , ... from the starting point, then there will be at most three distinct distances between pairs of points in adjacent positions around the circle. When there are three distances, the largest of the three always equals the sum of the other two. Unless is a rational multiple of , there will also be at least two distinct distances.
This result was conjectured by Hugo Steinhaus, and proved in the 1950s by Vera T. Sós, , and Stanisław Świerczkowski; more proofs were added by others later. Applications of the three-gap theorem include the study of plant growth and musical tuning systems, and the theory of light reflection within a mirrored square.
Statement
The three-gap theorem can be stated geometrically in terms of points on a circle. In this form, it states that if one places points on a circle, at angles of from the starting point, then there will be at most three distinct distances between pairs of points in adjacent positions around the circle. An equivalent and more algebraic form involves the fractional parts of multiples of a real number. It states that, for any positive real number and integer , the fractional parts of the numbers divide the unit interval into subintervals with at most three different lengths. The two problems are equivalent under a linear correspondence between the unit interval and the circumference of the circle, and a correspondence between the real number and the
Applications
Plant growth
In the study of phyllotaxis, the arrangements of leaves on plant stems, it has been observed that each successive leaf on the stems of many plants is turned from the previous leaf by the golden angle, approximately 137.5°. It has been suggested that this angle maximizes the sun-collecting power of the plant's leaves. If one looks end-on at a plant stem that has grown in this way, there will be at most three distinct angles between two leaves that are consecutive in the cyclic order given by this end-on view.
For example, in the figure, the largest of these three angles occurs three times, between the leaves numbered 3 and 6, between leaves 4 and 7, and between leaves 5 and 8. The second-largest angle occurs five times, between leaves 6 and 1, 9 and 4, 7 and 2, 10 and 5, and 8 and 3. And the smallest angle occurs only twice, between leaves 1 and 9 and between leaves 2 and 10. The phenomenon of having three types of distinct gaps depends only on fact that the growth pattern uses a constant rotation angle, and not on the relation of this angle to the golden ratio; the same phenomenon would happen for any other rotation angle, and not just for the golden angle. However, other properties of this growth pattern do depend on the golden ratio. For instance, the fact that golden ratio is a badly approximable number implies that points spaced at this angle along the Fermat spiral (as |

Wolfgang Maier first studied mathematics and economics at the Ludwig Maximilian University of Munich, graduating with diplomas in 1973. That same year he started studying medicine, also at the University of Munich. In 1980 he received his doctorate in medicine. In 1981 he started working at the Psychiatric University Clinic Mainz, first as a clinical scientist and doctor, before being promoted to senior physician and later to chief senior physician. In 1990 he qualified as a professor for the medical field of psychiatry. Concurrently, he went to the USA for several scientific work stays (esp. Cornell Medical School in New York City and Washington University School of Medicine in St. Louis, Missouri). He is a student of the deceased American and Canadian psychiatrists Gerald Klerman and Theodore Reich.
In 1995 he was appointed to the chair of psychiatry and psychotherapy and as the director of the Department of Psychiatry and Psychotherapy at the University of Bonn. In 2018 he was given emeritus status. Ever since he has been the medical director for Research and Education at the Gezeitenhaus Clinic in Bonn. In addition, he works as a visiting consultant at the German Neuroscience Center since 2020.
He used to be a spokesman for the competence networks "Dementia" (since 2005) and "Degenerative Dementia" (since 2007), both promoted by the German Federal Ministry for Education and Research.
From 2012 to 2014 he was President of the (DGPPN). In 2004, 2013 and 2014 he was President of the DGPPN Congresses. Also, in 2000 Maier founded the World Psychiatric Association (WPA)’s section "Genetics in Psychiatry" and the European Psychiatric Association (EPA)’s section "Prevention of Mental Disorders".
Since 2010 he has been a leading editor of the authoritative German medical journal "Der Nervenarzt" (The Neurologist). Moreover, Maier is a co-editor of the "European Archives of Psychiatry and Clinical Neuroscience".
Wolfgang Maier is a member of the National Academy of Sciences Leopoldina (neuroscience section). He is also a member of the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) (biomedical class) and a corresponding member of the Heidelberg Academy of Sciences and Humanities.

https://en.wikipedia.org/wiki/Elchanan%20Mossel | Elchanan Mossel () is a professor of mathematics at the Massachusetts Institute of Technology. His primary research fields are probability theory, combinatorics, and statistical inference.
Research
Mossel's research spans a number of topics across mathematics, statistics, economics, and computer science, including combinatorial statistics, discrete function inequalities, isoperimetry, game theory, social choice, computational complexity, and computational evolutionary biology.
His work on discrete Fourier analysis and functions with low influence includes important contributions such as the proof of the "Majority is Stablest" conjecture, together with Ryan O'Donnell and Krzysztof Oleszkiewicz, and the proof of the optimality of the Goemans–Williamson MAX-CUT algorithm (assuming the Unique Games Conjecture), with Subhash Khot, Guy Kindler and Ryan O’Donnell.
Mossel has worked on the reconstruction problem on trees.
He connected it to Steel's conjecture in Phylogenetic reconstruction, partially in work with Constantinos Daskalakis and Sébastien Roch.
These result links the extremality of the Ising model on the Bethe lattice to a phase transition in the amount of data required for statistical inference on phylogenetic trees.
With Joe Neeman and Allan Sly he established the role of the reconstruction problem on trees for the problem of detection in block models.
Education and career
Mossel graduated from the Open University of Israel in 1992 with a B.Sc. in mathematics. In 2000, he received his Ph.D. in mathematics from the Hebrew University. Mossel held a postdoctoral position at Microsoft Research and was a Miller Research Fellow at UC Berkeley before becoming a Professor at UC Berkeley, the Weizmann Institute, the University of Pennsylvania and finally MIT.
Mossel is a prolific scholar, with more than 100 coauthors and over 150 papers listed in MathSciNet as of 2022. He has advised 10 graduate students who have subsequently held faculty positions at UCLA, Princeton, UC Berkeley, Caltech, the University of Wisconsin, the University of Texas, the Chinese University of Hong Kong and the University of Minnesota.

https://en.wikipedia.org/wiki/Eugene%20Isaacson | Eugene Isaacson (1919–2008), was a US mathematician who pioneered modern numerical analysis. He was a mathematics and physics graduate of City College in New York, he then entered the graduate program in mathematics at New York University under the supervision of Kurt Otto Friedrichs, gaining a PhD on water waves on sloping beaches in 1949. His academic career was then spent at the Courant Institute until his retirement.
Despite an initial interest in topology, Isaacson worked for most of his career in applied and computational mathematics and is best known for his work on the numerical solution of differential equations. His book with Herbert Keller Analysis of Numerical Methods was a leading textbook at the time.
He served as editor for Mathematics of Computation and the SIAM Journal on Numerical Analysis.
A special issue of Mathematics of Computation was published in 1989 to celebrate his 70th birthday. The contributors included his sons David and Eli Isaacson, also mathematicians, who wrote a paper together for this volume. The paper is dedicated to their father and their mother Muriel "for making this collaboration possible".

https://en.wikipedia.org/wiki/Pyragas%20method | In the mathematics of chaotic dynamical systems, in the Pyragas method of stabilizing a periodic orbit, an appropriate continuous controlling signal is injected into the system, whose intensity is nearly zero as the system evolves close to the desired periodic orbit but increases when it drifts away from the desired orbit. Both the Pyragas and OGY (Ott, Grebogi and Yorke) methods are part of a general class of methods called "closed loop" or "feedback" methods which can be applied based on knowledge of the system obtained through solely observing the behavior of the system as a whole over a suitable period of time.
The method was proposed by Lithuanian physicist .

The method was introduced in Jonas Kubilius's monograph Tikimybiniai metodai skaičių teorijoje (published in Lithuanian in 1959) / Probabilistic Methods in the Theory of Numbers (published in English in 1964) .
Eugenijus Manstavičius and Fritz Schweiger wrote about Kubilius's work in 1992, "the most impressive work has been done on the statistical theory of arithmetic functions which almost created a new research area called Probabilistic Number Theory. A monograph (Probabilistic Methods in the Theory of Numbers) devoted to this topic was translated into English in 1964 and became very influential."

https://en.wikipedia.org/wiki/Variety%20of%20finite%20semigroups | In mathematics, and more precisely in semigroup theory, a variety of finite semigroups is a class of semigroups having some nice algebraic properties. Those classes can be defined in two distinct ways, using either algebraic notions or topological notions. Varieties of finite monoids, varieties of finite ordered semigroups and varieties of finite ordered monoids are defined similarly.
This notion is very similar to the general notion of variety in universal algebra.
Definition
Two equivalent definitions are now given.
Algebraic definition
A variety V of finite (ordered) semigroups is a class of finite (ordered) semigroups that:
is closed under division.
is closed under taking finite Cartesian products.
The first condition is equivalent to stating that V is closed under taking subsemigroups and under taking quotients. The second property implies that the empty product—that is, the trivial semigroup of one element—belongs to each variety. Hence a variety is necessarily non-empty.
A variety of finite (ordered) monoids is a variety of finite (ordered) semigroups whose elements are monoids. That is, it is a class of (ordered) monoids satisfying the two conditions stated above.
Topological definition
In order to give the topological definition of a variety of finite semigroups, some other definitions related to profinite words are needed.
Let A be an arbitrary finite alphabet. Let A+ be its free semigroup. Then let be the set of profinite words over A. Given a semigroup morphism , let be the unique continuous extension of to .
A profinite identity is a pair u and v of profinite words. A semigroup S is said to satisfy the profinite identity u = v if, for each semigroup morphism , the equality holds.
A variety of finite semigroups is the class of finite semigroups satisfying a set of profinite identities P.
A variety of finite monoids is defined like a variety of finite semigroups, with the difference that one should consider monoid morphisms instead of semigroup morphisms .
A variety of finite ordered semigroups/monoids is also given by a similar definition, with the difference that one should consider morphisms of ordered semigroups/monoids.
Examples
A few examples of classes of semigroups are given. The first examples uses finite identities—that is, profinite identities whose two words are finite words. The next example uses profinite identities. The last one is an example of a class that is not a variety.
More examples are given in the article Special classes of semigroups.
Using finite identities
The most trivial example is the variety S of all finite semigroups. This variety is defined by the empty set of profinite equalities. It is trivial to see that this class of finite semigroups is closed under subsemigroups, finite products, and quotients.
The second most trivial example is the variety 1 containing only the trivial semigroup. This variety is defined by the set of profinite equalities {x = y}. Intuitively, this equ |
https://en.wikipedia.org/wiki/Clark%20Barwick | Clark Edward Barwick (born January 9, 1980) is an American mathematician and professor of pure mathematics at the University of Edinburgh. His research is centered around homotopy theory, algebraic K-theory, higher category theory, and related areas.
Early life and education
Barwick grew up in North Carolina, and in 2001 completed his BS in mathematics at the University of North Carolina at Chapel Hill. Barwick was then a graduate student at the University of Pennsylvania, and received his PhD in mathematics in 2005 under the direction of Tony Pantev.
Career
Barwick held postdoctoral fellowships at the Mathematisches Institut Göttingen (2005–2006) and at the Matematisk Institutt, Universitetet i Oslo (2006–2007). Barwick spent the year 2007–2008 at the Institute for Advanced Study, and from 2008–2010 was a Benjamin Peirce Lecturer at Harvard. In 2010 Barwick became an assistant professor at MIT, and in 2013 he became the Cecil and Ida Green Career Development Assistant Professor of Mathematics. In 2015 Barwick was a Fulbright visiting professor at the University of Glasgow and was promoted to Cecil and Ida Green Career Development Associate Professor of Mathematics at MIT, a position which he held until he became a reader at the University of Edinburgh in 2017. In 2020, Barwick was promoted to a professor at the University of Edinburgh.
Research and notable works
A theme in Barwick's work is the homotopy theory of higher categories. In his early career, he frequently collaborated with Dan Kan; much of their work was concerned with models for the homotopy theory of homotopy theories. In his joint work with Chris Schommer-Pries, Barwick and Schommer-Pries proved a unicity theorem for the homotopy theory of (∞,n)-categories.
Barwick has also made contributions to algebraic K-theory. In particular, Barwick defined higher-categorical generalizations of Waldhausen categories and Waldhausen's S-construction and used these to extend Waldhausen's K-theory to the setting of (∞,1)-categories. Using this new theory, he proved the Theorem of the Heart for Waldhausen K-theory. In joint work with John Rognes, he generalized Quillen's Q-construction to the higher-categorical setting, providing higher-categorical generalizations of Quillen's Theorem B as well as Quillen's dévissage argument in the process. Much of his recent work has concerned equivariant algebraic K-theory and equivariant homotopy theory. Barwick won the 2019 Berwick Prize of the London Mathematical Society for his paper "On the algebraic K-theory of higher categories" where he "proves that Waldhausen's algebraic K-theory is the universal homology theory for ∞-categories, and uses this universality to reprove the major fundamental theorems of the subject in this new context."

https://en.wikipedia.org/wiki/Bing%E2%80%93Borsuk%20conjecture | In mathematics, the Bing–Borsuk conjecture states that every -dimensional homogeneous absolute neighborhood retract space is a topological manifold. The conjecture has been proved for dimensions 1 and 2, and it is known that the 3-dimensional version of the conjecture implies the Poincaré conjecture.
Definitions
A topological space is homogeneous if, for any two points , there is a homeomorphism of which takes to .
A metric space is an absolute neighborhood retract (ANR) if, for every closed embedding (where is a metric space), there exists an open neighbourhood of the image which retracts to .
There is an alternate statement of the Bing–Borsuk conjecture: suppose is embedded in for some and this embedding can be extended to an embedding of . If has a mapping cylinder neighbourhood of some map with mapping cylinder projection , then is an approximate fibration.
History
The conjecture was first made in a paper by R. H. Bing and Karol Borsuk in 1965, who proved it for and 2.
Włodzimierz Jakobsche showed in 1978 that, if the Bing–Borsuk conjecture is true in dimension 3, then the Poincaré conjecture must also be true.
The Busemann conjecture states that every Busemann -space is a topological manifold. It is a special case of the Bing–Borsuk conjecture. The Busemann conjecture is known to be true for dimensions 1 to 4.

https://en.wikipedia.org/wiki/Emily%20Willbanks | Emily Willbanks (born Emily West, November 25, 1930 – February 18, 2007) was a scientist at the Los Alamos National Laboratory from 1954–1990. She made advancements in the fields of mathematics, computing, and data systems. She used her background in physics and mathematics to contribute to defense weapons and high-performance storage systems at Los Alamos. She was instrumental in the advancement of a major weather centre in England, was involved in many classified projects for the government, and revolutionized the mass data storage system.
Life
Early years and education
Emily West was born on November 25, 1930, in Fort Lauderdale, Florida. Her father, Frank M. West, was the superintendent for a private beach estate, and her mother was a homemaker. She was their only child. West attended the public high school. From a young age she expressed great interest in mathematics and science. West studied science at Duke University beginning in 1948. After her first year she received a scholarship for academic excellence and was the sole female physics major in her graduating class. She earned a B.S. in math and physics in 1952. She continued her education at the University of New Mexico where she completed a master's degree in physics in 1957.
Early career
West worked as an engineering aide in mathematics at Pratt & Whitney Aircraft Co from 1952 to 1954. Her work there involved hand calculations of heat flow and fluid dynamics for a feasibility study on nuclear-powered aircraft, in partnership with General Electric.
Los Alamos National Laboratory
West began working at the Los Alamos National Laboratory in 1954. While at Los Alamos National Laboratory her initial work involved hand calculations. This evolved into working with the MANIAC I computer for weapons applications. She continued working in the weapons division until the early seventies. She worked under Roger Lazarus in the Computer Division at Los Alamos National Laboratory until she retired in 1990. Her work in the computing department involved the design and maintenance of computer storage, including a project to design a clustered file system. Her work for this project included software development and computerizing weapons data. She adapted the same software in an English weather center database, the Meteorological Archival and Retrieval System.
Personal life
West met Eugene Willbanks at Los Alamos. At the time, she was working in the weapons department while Eugene worked in the computing division. They married in 1959, but had no children. Her husband died from a brain tumour in 1994. Emily Willbanks died on February 18, 2007, in Los Alamos, New Mexico.
Legacy and major projects
Weapons applications
At the Los Alamos National Laboratory (LANL), Willbanks (née West) and a group of five or six others used their pre-written code to analyze weapons that were designed by the engineers at LANL. Their analysis produced data from simulated explosions and provided feedback to the eng |

https://en.wikipedia.org/wiki/Basin-hopping | In applied mathematics, Basin-hopping is a global optimization technique that iterates by performing random perturbation of coordinates, performing local optimization, and accepting or rejecting new coordinates based on a minimized function value. The algorithm was described in 1997 by David J. Wales and Jonathan Doye. It is a particularly useful algorithm for global optimization in very high-dimensional landscapes, such as finding the minimum energy structure for molecules. The method is inspired from Monte-Carlo Minimization first suggested by Li and Scheraga.

https://en.wikipedia.org/wiki/Geely%20Yuanjing%20X3 | The Geely Yuanjing X3 is a subcompact CUV produced by Chinese manufacturer Geely. An electric variant featuring a special color and trim redesign was rebadged as the Geometry EX3 or Kungfu Cow under the Geometry brand from 2021.
Overview
The Geely Yuanjing X3 was revealed in July 2017, and debuted in Q3 2017. The Yuanjing X3 was formerly known as the Yuanjing V3 during development, and was renamed prior to launch to fit into the later confirmed Geely Yuanjing crossover product series slotting between the Geely Yuanjing X1 and Geely Yuanjing X6.
The Yuanjing X3 is based on the Geely Englon SC5-RV from 2011 to 2014, and utilizes the same engine, a 1.5 liter engine previously producing 94 hp for the Englon SC5-RV. The same 1.5 liter engine was tuned up to 102 hp and mated to a 5-speed manual gearbox or a 4-speed automatic gearbox.
Geely Yuanjing X3 Pro and Maple/ Livan X3 Pro
A facelift was launched in April 2021 called the Yuanjing X3 Pro. The X3 Pro update is powered by a 1.5-litre engine producing 109 hp and mated to a CVT gearbox. The Yuanjing X3 Pro was also rebadged and launched in May 2022 as the Maple X3 Pro as the first pure gasoline-powered vehicle under the relaunched Maple brand.
Maple 30X EV
The Maple 30X EV is a subcompact electric crossover SUV based on the Geely Yuanjing X3 with the exterior body being essentially a rebadge. The Maple 30x result of a partnership between Geely and Kandi Technologies. It was launched by the affiliate company of Kandi Technologies Group, Inc., Fengsheng Automotive in July 2020. Fengsheng also launched a mobility version of the Maple 30x customized for the urban mobility market.
The motor of the Maple 30X has a maximum output of 70kW (94 hp) and a maximum torque of 180N.m, the electric driving range on one full charge is up to 306 km or 190 miles. The Maple 30X comes with express charging and standard charging options. Express charging enables the vehicle to be charged to 80% in 30 minutes. A home plug-in charging feature is also available for all future Maple brand electric vehicles.
Geometry EX3
The Geometry EX3 launched in 2021 is a subcompact electric crossover SUV based on the Geely Yuanjing X3. It comes with a 37.23 kWh battery providing a claimed range of 322 kilometers (200 miles). The EX3 was only sold in 2021 and was replaced by the completely redesigned Geometry E in 2022.

https://en.wikipedia.org/wiki/Nilsemigroup | In mathematics, and more precisely in semigroup theory, a nilsemigroup or nilpotent semigroup is a semigroup whose every element is nilpotent.
Definitions
Formally, a semigroup S is a nilsemigroup if:
S contains 0 and
for each element a∈S, there exists a positive integer k such that ak=0.
Finite nilsemigroups
Equivalent definitions exists for finite semigroup. A finite semigroup S is nilpotent if, equivalently:
for each , where is the cardinality of S.
The zero is the only idempotent of S.
Examples
The trivial semigroup of a single element is trivially a nilsemigroup.
The set of strictly upper triangular matrix, with matrix multiplication is nilpotent.
Let a bounded interval of positive real numbers. For x, y belonging to I, define as . We now show that is a nilsemigroup whose zero is n. For each natural number k, kx is equal to . For k at least equal to , kx equals n. This example generalize for any bounded interval of an Archimedean ordered semigroup.
Properties
A non-trivial nilsemigroup does not contain an identity element. It follows that the only nilpotent monoid is the trivial monoid.
The class of nilsemigroups is:
closed under taking subsemigroups
closed under taking quotients
closed under finite products
but is not closed under arbitrary direct product. Indeed, take the semigroup , where is defined as above. The semigroup S is a direct product of nilsemigroups, however its contains no nilpotent element.
It follows that the class of nilsemigroups is not a variety of universal algebra. However, the set of finite nilsemigroups is a variety of finite semigroups. The variety of finite nilsemigroups is defined by the profinite equalities .

https://en.wikipedia.org/wiki/Legendre%20moment | In mathematics, Legendre moments are a type of image moment and are achieved by using the Legendre polynomial. Legendre moments are used in areas of image processing including: pattern and object recognition, image indexing, line fitting, feature extraction, edge detection, and texture analysis. Legendre moments have been studied as a means to reduce image moment calculation complexity by limiting the amount of information redundancy through approximation.
Legendre moments

https://en.wikipedia.org/wiki/Forbes-Mabry%20House | The Forbes-Mabry House is a historic house in Clarksville, Tennessee, U.S..
History
The house was built in 1859 for William A. Forbes, a professor of Mathematics and Natural History at Stewart College, later known as Rhodes College, who was also a tobacco investor and served on the board of the Memphis, Clarksville and Louisville Railroad. During the American Civil War, Forbes joined the Confederate States Army, and he died at the Second Battle of Bull Run.
Congressman Cave Johnson, Mrs. Forbes' step-father, lived in the house with her during the Civil War. His three sons from another marriage also served in the CSA - two of them in the 14th Tennessee Infantry under Col. Forbes. Mrs. Forbes lived in the house until her death in 1891, and it was purchased by Thomas L. Mabry in 1899. It remained in the Mabry family until 1973.
By 2011, it was the residence of Patsy Sharpe, an ornament designer.
Architectural significance
The house was designed in the Italianate architectural style. It has been listed on the National Register of Historic Places since January 12, 1995.

https://en.wikipedia.org/wiki/Operator%20monotone%20function | In linear algebra, the operator monotone function is an important type of real-valued function, fully classified by Charles Löwner in 1934. It is closely allied to the operator concave and operator concave functions, and is encountered in operator theory and in matrix theory, and led to the Löwner–Heinz inequality.
Definition
A function defined on an interval is said to be operator monotone if whenever and are Hermitian matrices (of any size/dimensions) whose eigenvalues all belong to the domain of and whose difference is a positive semi-definite matrix, then necessarily
where and are the values of the matrix function induced by (which are matrices of the same size as and ).
Notation
This definition is frequently expressed with the notation that is now defined.
Write to indicate that a matrix is positive semi-definite and write to indicate that the difference of two matrices and satisfies (that is, is positive semi-definite).
With and as in the theorem's statement, the value of the matrix function is the matrix (of the same size as ) defined in terms of its 's spectral decomposition by
where the are the eigenvalues of with corresponding projectors
The definition of an operator monotone function may now be restated as:
A function defined on an interval said to be operator monotone if (and only if) for all positive integers and all Hermitian matrices and with eigenvalues in if then

https://en.wikipedia.org/wiki/Reduction%20compass | The reduction compass or proportional dividers is a geometry tool with asymmetric-length branches to allow performing homothetic transformations, reproducing a pattern while enlarging or reducing its size and conserving angles. It was invented by Fabrizio Mordente before 1567.
Use and principle
The reduction compass is made of two branches, with two points each. Several types exist, including the following:
simple reduction compass: the pivot is fixed, and the enlargement factor is determined by the length difference between the small and long end of the branches;
mobile-headed reduction compass: the pivot is mounted on a slide, and its position determines the enlargement factor.
The underlying principle is that of proportionality of the sides of two similar isosceles triangles.
The reduction compass was customarily used in geography to change the scale of maps.

https://en.wikipedia.org/wiki/Crinkled%20arc | In mathematics, and in particular the study of Hilbert spaces, a crinkled arc is a type of continuous curve. The concept is usually credited to Paul Halmos.
Specifically, consider where is a Hilbert space with inner product We say that is a crinkled arc if it is continuous and possesses the crinkly property: if then that is, the chords and are orthogonal whenever the intervals and are non-overlapping.
Halmos points out that if two nonoverlapping chords are orthogonal, then "the curve makes a right-angle turn during the passage between the chords' farthest end-points" and observes that such a curve would "seem to be making a sudden right angle turn at each point" which would justify the choice of terminology. Halmos deduces that such a curve could not have a tangent at any point, and uses the concept to justify his statement that an infinite-dimensional Hilbert space is "even roomier than it looks".
Writing in 1975, Richard Vitale considers Halmos's empirical observation that every attempt to construct a crinkled arc results in essentially the same solution and proves that is a crinkled arc if and only if, after appropriate normalizations,
where is an orthonormal set. The normalizations that need to be allowed are the following: a) Replace the Hilbert space H by its smallest closed subspace containing all the values of the crinkled arc; b) uniform scalings; c) translations; d) reparametrizations.
Now use these normalizations to define an equivalence relation on crinkled arcs if any two of them become identical after any sequence of such normalizations. Then there is just one equivalence class, and Vitale's formula describes a canonical example.

https://en.wikipedia.org/wiki/Jacques%20Riguet | Jacques Riguet (1921 to October 20, 2013) was a French mathematician known for his contributions to algebraic logic and category theory. According to Gunther Schmidt and Thomas Ströhlein, "Alfred Tarski and Jacques Riguet founded the modern calculus of relations".
Career
Already at his lycée, Riguet was impressed by the power of geometric reasoning. He studied Louis Couturat and Bourbaki, who made contributions to logic and set theory.
Riguet studied higher mathematics with Albert Châtelet and was introduced to lattices. In 1948 he published "Relations binaires, fermetures, correspondances de Galois" which revived the calculus of binary relations.
He published his thesis Fondements de la Theorie de Relations Binaires in October 1951.
In 1954 Riguet gave a plenary address at the International Congress of Mathematicians in Amsterdam, speaking on the applications of binary relations to algebra and machine theory. For a time, Riguet attended the seminary of Jacques Lacan.
Riguet was employed at Centre national de la recherche scientifique until 1957.
Relations
In Riguet's work the composition of relations is the basis for characterizing relations, replacing the element-wise descriptions that use logical formulations. For example, he described the Schröder rules. His work was reviewed in Journal of Symbolic Logic by Øystein Ore.
Some of Riguet’s contributions can be described using structure of the logical matrix associated with a relation. If u and v are logical vectors, then their logical outer product produces the associated logical matrix Riguet calls the associated relation a rectangular relation, and if it happens to be symmetric it is a square relation.
In 1950 he submitted "Sur les ensembles reguliers de relations binaires", and an article on difunctional relations, those with logical matrix in a block diagonal form.
The following year he provided an algebraic characterization of heterogeneous relations with a logical matrix comparable to a Ferrers diagram. Since Ferrers diagrams order the partition of an integer, Riguet extended order theory beyond relations restricted to one set.
In 1954 Riguet described the extension of the calculus of binary relations to a calculus of Boolean matrices.
Category theory
In 1958 Riguet went to Zurich, working with IBM , studying category theory. He published the following papers on that topic:
1962: "Programmation et theorie des categories", in Proceedings of Symposium on Symbolic Languages and Data Processing, Rome (1961), pp 88–98, Gordon & Breach
1973: "Probabilites et theorie de la decision du point de vue de la theorie des categories" (Amiens colloquium) Cahiers de Topologie et Géométrie Différentielle Catégoriques 14(2)

GEKKO works on all platforms and with Python 2.7 and 3+. By default, the problem is sent to a public server where the solution is computed and returned to Python. There are Windows, MacOS, Linux, and ARM (Raspberry Pi) processor options to solve without an Internet connection. GEKKO is an extension of the APMonitor Optimization Suite but has integrated the modeling and solution visualization directly within Python. A mathematical model is expressed in terms of variables and equations such as the Hock & Schittkowski Benchmark Problem #71 used to test the performance of nonlinear programming solvers. This particular optimization problem has an objective function and subject to the inequality constraint and equality constraint . The four variables must be between a lower bound of 1 and an upper bound of 5. The initial guess values are . This optimization problem is solved with GEKKO as shown below.

https://en.wikipedia.org/wiki/Jouanolou%27s%20trick | In algebraic geometry, Jouanolou's trick is a theorem that asserts, for an algebraic variety X, the existence of a surjection with affine fibers from an affine variety W to X. The variety W is therefore homotopy-equivalent to X, but it has the technically advantageous property of being affine. Jouanolou's original statement of the theorem required that X be quasi-projective over an affine scheme, but this has since been considerably weakened.
Jouanolou's construction
Jouanolou's original statement was:
If X is a scheme quasi-projective over an affine scheme, then there exists a vector bundle E over X and an affine E-torsor W.
By the definition of a torsor, W comes with a surjective map to X and is Zariski-locally on X an affine space bundle.
Jouanolou's proof used an explicit construction. Let S be an affine scheme and . Interpret the affine space as the space of (r + 1) × (r + 1) matrices over S. Within this affine space, there is a subvariety W consisting of idempotent matrices of rank one. The image of such a matrix is therefore a point in X, and the map that sends a matrix to the point corresponding to its image is the map claimed in the statement of the theorem. To show that this map has the desired properties, Jouanolou notes that there is a short exact sequence of vector bundles:
where the first map is defined by multiplication by a basis of sections of and the second map is the cokernel. Jouanolou then asserts that W is a torsor for .
Jouanolou deduces the theorem in general by reducing to the above case. If X is projective over an affine scheme S, then it admits a closed immersion into some projective space . Pulling back the variety W constructed above for along this immersion yields the desired variety W for X. Finally, if X is quasi-projective, then it may be realized as an open subscheme of a projective S-scheme. Blow up the complement of X to get , and let denote the inclusion morphism. The complement of X in is a Cartier divisor, and therefore i is an affine morphism. Now perform the previous construction for and pull back along i.
Thomason's construction
Robert Thomason observed that, by making a less explicit construction, it was possible to obtain the same conclusion under significantly weaker hypotheses. Thomason's construction first appeared in a paper of Weibel. Thomason's theorem asserts:
Let X be a quasicompact and quasiseparated scheme with an ample family of line bundles. Then an affine vector bundle torsor over X exists.
Having an ample family of line bundles was first defined in SGA 6 Exposé II Définition 2.2.4. Any quasi-projective scheme over an affine scheme has an ample family of line bundles, as does any separated locally factorial Noetherian scheme.
Thomason's proof abstracts the key features of Jouanolou's. By hypothesis, X admits a set of line bundles L0, ..., LN and sections s0, ..., sN whose non-vanishing loci are affine and cover X. Define Xi to be the non-vanishing lo |

https://en.wikipedia.org/wiki/L%C3%A9vy%E2%80%93Steinitz%20theorem | In mathematics, the Lévy–Steinitz theorem identifies the set of values to which rearrangements of an infinite series of vectors in Rn can converge. It was proved by Paul Lévy in his first published paper when he was 19 years old. In 1913 Ernst Steinitz filled in a gap in Lévy's proof and also proved the result by a different method.
In an expository article, Peter Rosenthal stated the theorem in the following way.
The set of all sums of rearrangements of a given series of vectors in a finite-dimensional real Euclidean space is either the empty set or a translate of a subspace (i.e., a set of the form v + M, where v is a given vector and M is a linear subspace).

https://en.wikipedia.org/wiki/Julia%20Robinson%20Mathematics%20Festival | The Julia Robinson Mathematics Festival (JRMF) is an educational organization that sponsors locally organized mathematics festivals and online webinars targeting K–12 students. The events are designed to introduce students to mathematics in a collaborative and non-competitive forum.
History
In the 1970s, Saint Mary's College of California produced a mathematics contest that was popular with secondary schools throughout the San Francisco Bay Area. In 2005, Nancy Blachman attended an education forum sponsored by the Mathematical Sciences Research Institute (MSRI) and remembered how the Saint Mary's contest had inspired her as a student. Unfortunately, the contest no longer existed. Seeking to possibly resurrect the contest, Blachman and MSRI development director Jim Sotiros reached out to colleagues in the educational community. One response was from local high school math teacher Joshua Zucker, who also remembered the contest and even had saved a book of problems from it. Sotiros suggested that Blachman and her husband David desJardins fund MSRI in order to hire Zucker to recreate a program in the style of the Saint Mary’s Math Contest. Blachman and Zucker became co-founders and organized their first event in 2007. They called it a festival rather than a contest because they wanted to emphasize collaboration, creativity and fun rather than competition. They named the festival after Julia Robinson, a mathematician renowned for her contributions to decision problems. In fact, her work on Hilbert's 10th problem played a crucial role in its ultimate resolution. Blachman felt that such a woman would provide a role model for young girls and would show that one need not be male to be a great mathematician.
When they sent out invitations to local schools, the response was so overwhelming that, in order to have enough space, they prevailed upon Google in nearby Mountain View to host the first festival. A second festival was hosted in 2008 by Pixar Animation Studios in Emeryville. Enthusiasm and interest have spurred strong growth, and since then, there have been festivals at Princeton University (and its greater community); Stanford University; and University of California, Berkeley, and throughout the United States, as well as in Europe and Asia.
As of December 2019, JRMF will have hosted nearly 500 events in 25 states, the District of Columbia, one territory (Puerto Rico), and 15 foreign countries. In 2020, they hosted over 120 Festivals—an increase of more than 50% over 2018. The services JRMF offer continue to be free of charge. The target audience is third- to eighth-graders. Our festivals are attended by 30 to 50 percent girls. The Julia Robinson Mathematics Festival has been invited to host festivals and tables at events such as the Joint Mathematics Meeting and MAA Mathfest. In December 2019, they celebrated Julia Robinson's 100th birthday with a festival in her hometown.

https://en.wikipedia.org/wiki/Statistics%20of%20the%20Colonies%20of%20the%20British%20Empire | Statistics of the Colonies of the British Empire (or more completely, Statistics of the Colonies of the British Empire in the West Indies, South America, North America, Asia, Austral-Asia, Africa, and Europe) is a work by Robert Montgomery Martin which comprises a number of different statistics to measure the well-being of the British Colonies in the late 18th until mid 19th century. It was first published in 1839 by W. H. Allen & Co. roughly a year after it was commenced in February 1838.
The book was published in Royal Octavo (10" by 6¼") and contains roughly 1000 pages, arranged in double columns. In 1839, the book costed £2. 2s. which is approximately £233 in 2018.
Background
Featured in the preface of the book, it is reported that in 1836-7, the Committee of the House of Commons wanted to know about the financial conditions of the colonies and thus wanted to compile the colonial Blue Book into a form suitable for publication.
Due to time and expenditure (it was estimated to cost about £10,000) the initiative was abandoned by the British Empire. Martin, who at that time was a founding member of the Statistical Society of London (1834), decided to take it upon himself to compile the blue books from all the British Colonies of the time.
The Blue books consist of three blank books that were sent to the colonies each year so to be filled in where two of them were returned to Downing Street and another remained in the possession of the colony's Governor.
In order to do that, he wrote a letter to Sir George Grey who was at the time the Under-Secretary of State for the Colonies, stating his request to access the blue books for this project which he completed using his own expenses and without official assistance.
Martin received permission from Lord Glenelg, the Secretary of State for War and the Colonies at the time, to access the blue books and other statistical information regarding the colonies. He was then given his own office in Downing Street to complete the book with his assistant, Frederick Medley. Around 250 volumes of the blue books and a number of various documents were examined and sorted out into a book fit for publication, a which that took him roughly a year to finish.
Stated in the preface, his motivation for compiling the blue books was not only to help measure the decline or progress of the colonies but to also compile it in a way that would bring about the feeling of pride amongst the citizens of Britain. This was in line with Martin's interest which was colonialism as can be seen in his other publications that mostly touched on the topic of the British Colonies. In 1840, he founded and became the editor of the Colonial Magazine and Commercial Maritime Journal.

The Chalukyas (IAST: Cālukya) of Navasarika (modern Navsari) were an Indian dynasty that ruled parts of present-day Gujarat and Maharashtra during 7th and 8th centuries, as vassals of the Chalukyas of Vatapi. They are also known as the "Early Chalukyas of Gujarat" (as opposed to the later Chalukyas of Gujarat).
In the late 660s, the Vatapi Chalukya king Vikramaditya I appointed his brother Dharashraya Jayasimhavarman as the governor of the north-western parts of his kingdom, which included southern Gujarat (Lata), Nashik region, and northern Konkan. Dharashraya's eldest son Shryashraya Shiladitya died before him, and he was succeeded by his younger sons, first Jayashraya Mangalarasa, and then Avanijanashraya Pulakeshin. Avanijanashraya is best known for repulsing an Arab invasion from the Umayyad Caliphate near Navsari, a feat recorded in his 738-739 inscription. After his reign, the history of this Chalukya branch is uncertain: their territory subsequently came under the Rashtrakuta control.
Dharashraya Jayasimhavarman
The Navsari branch of the Chalukyas was established by Dharashraya Jayasimhavarman (IAST: Dharāśraya Jaya-siṃha-varman), who was a son of the Vatapi Chalukya king Pulakeshin II, and a younger brother of Pulakeshin's successor Vikramaditya I. Sometime before 667-670 CE, Vikramaditya appointed Dharashraya as the governor of the north-western Chalukya territories, which included parts of present-day southern Gujarat, and the Konkan and Nashik region of Maharashtra.
Dharashraya is attested by his Nashik inscription, which is dated to 20 or 21 March 685 (year 436 of the Kalachuri era). This Sanskrit-language inscription records the grant of the Dhondhaka village in the Nasikya vishaya (Nashik province) to a Brahmana named Trivikrama.
The Nashik inscription states that Dharashraya defeated and routed the army of a king named Vajjada, between the Mahi |

https://en.wikipedia.org/wiki/Thyra%20Eibe | Thyra Eibe (3 November 1866 – 4 January 1955) was a Danish mathematician and translator, the first woman to earn a mathematics degree from the University of Copenhagen. She is known for her translation of Euclid's Elements into the Danish Language.
Education and career
Eibe was one of ten children of a Copenhagen bookseller. After completing a degree in historical linguistics in 1889 from N. Zahle's School (then a girls' school), Eibe studied mathematics at the University of Copenhagen, and earned a cand.mag. there in 1895. She returned to Zahle's School as a teacher, also teaching boys at Slomann's School and becoming the first woman to become an advanced mathematics teacher for boys in Denmark. In 1898 she moved to H. Adler Community College, later to become the , where she remained until 1934, serving as principal for a year in 1929–1930.
Contributions
In undertaking her translation of Euclid, Eibe was motivated by the earlier work of Danish historian Johan Ludvig Heiberg, who published an edition of Euclid's Elements in its original Greek, with translations into Latin.
As well as her translations, Eibe wrote several widely used Danish mathematics textbooks.
Recognition
In 1942, she was given the Tagea Brandt Rejselegat, an award for Danish woman who have made a significant contribution in science, literature or art.

Early life and education
He was born in Hartford, Connecticut, to Howard Alexander Camp and Alice Amelia (Parsons) Camp.
He graduated from Wesleyan University in 1901, where he was a member of the Eclectic Society and Phi Beta Kappa. He studied under Professor of English literature, Caleb Thomas Winchester, and gave an address at the Commencement.
He earned a B.A. from Harvard in 1903, and M.A. in 1907, and Ph.D. from Yale in 1911. His thesis was on the Convergence of Singular Integrals and his advisor was James Pierpont.
Career
He taught at Oak Grove Seminary in Vassalboro, Maine, from 1902–1903, was an instructor in Mathematics at the Massachusetts Institute of Technology from 1903–1904, at Wesleyan from 1904–1905, at Harvard from 1906–1907, and again at Wesleyan from 1907–1909.
He was named an Associate Professor of Mathematics at Wesleyan in 1909, and a Professor in 1914. He was a chair of the department. He was acting director of the Van Vleck Observatory from 1918–1920. He was involved with Mathematics at Wesleyan until 1948.
in the early 1920s Camp switched from analysis to mathematical statistics and spent a year in London studying with Karl Pearson. He was a founder and early President of the Institute of Mathematical Statistics, Vice President of the American Statistical Association, and a member of the American Mathematical Society. Camp was named a Fellow of the American Statistical Association in 1936.

https://en.wikipedia.org/wiki/Kleiman%27s%20theorem | In algebraic geometry, Kleiman's theorem, introduced by , concerns dimension and smoothness of scheme-theoretic intersection after some perturbation of factors in the intersection.
Precisely, it states: given a connected algebraic group G acting transitively on an algebraic variety X over an algebraically closed field k and morphisms of varieties, G contains a nonempty open subset such that for each g in the set,
either is empty or has pure dimension , where is ,
(Kleiman–Bertini theorem) If are smooth varieties and if the characteristic of the base field k is zero, then is smooth.
Statement 1 establishes a version of Chow's moving lemma: after some perturbation of cycles on X, their intersection has expected dimension.
Sketch of proof
We write for . Let be the composition that is followed by the group action .
Let be the fiber product of and ; its set of closed points is
.
We want to compute the dimension of . Let be the projection. It is surjective since acts transitively on X. Each fiber of p is a coset of stabilizers on X and so
.
Consider the projection ; the fiber of q over g is and has the expected dimension unless empty. This completes the proof of Statement 1.
For Statement 2, since G acts transitively on X and the smooth locus of X is nonempty (by characteristic zero), X itself is smooth. Since G is smooth, each geometric fiber of p is smooth and thus is a smooth morphism. It follows that a general fiber of is smooth by generic smoothness.

https://en.wikipedia.org/wiki/Clara%20Eliza%20Smith | Clara Eliza Smith (May 20, 1865 – May 12, 1943) was an American mathematician specializing in complex analysis who became the Helen Day Gould Professor of Mathematics at Wellesley College.
Smith was the daughter of Georgiana and Edward Smith, of Northford, Connecticut. She studied at Mount Holyoke College, then a seminary, while also studying art at Yale University. Her studies in the seminary program included geometry and trigonometry, but the college did not offer degrees at that time. She completed the program in 1885. After working as an art teacher at the Bloomsburg State Normal School in Pennsylvania from 1889 until 1898, she returned to Yale for graduate study in mathematics in 1901, along the way earning a bachelor's degree by examination from Mount Holyoke in 1902. In 1904, she completed a Ph.D. at Yale University; her dissertation, Representation of an Arbitrary Function by means of Bessel's Functions, concerned Bessel functions.
She joined the Wellesley faculty in 1906, as a substitute teacher of mathematics. She then briefly taught at the Western College for Women in Oxford, Ohio, but by 1908 she had returned to Wellesley as a regular instructor. In 1924 she became the Helen Day Gould Professor. She retired in 1934.
At Wellesley, Smith became known for her course in complex analysis. She also wrote two textbooks with Helen Abbot Merrill, Selected Topics in Higher Algebra (Norwood, 1914) and A First Course in Higher Algebra (Macmillan, 1917).

https://en.wikipedia.org/wiki/Hits%20per%20run | In baseball statistics, hits per run (H/R), also known as hit conversion rate (HCR) is the ratio between hits and runs scored. It is the average number of hits it takes to score a run. H/R is the measure of the effectiveness of hitting in scoring a run. Teams having a lower hits-to-run ratio would likely have a good offense and could be expected to win more games.
For example, the 1927 New York Yankees, who had a record of 110–44 and are considered one of the greatest teams in Major League Baseball (MLB) history, had 1644 hits and scored 976 runs—a ratio of 1.68 hits per runs. Conversely, the 1916 Philadelphia Athletics, who had a record of 36–117 and are considered one of the worst teams, had 1212 hits and scored 447 runs—a ratio of 2.71 hits per run.
Between 2008 and 2017, the average hits-to-run ratio in MLB (based on total hits and runs made by all teams during each regular season) varied between 1.87 (2017) and 2.08 (2013), meaning that it generally takes MLB teams about two hits to score a run.

https://en.wikipedia.org/wiki/Home%20runs%20per%20hit | In baseball statistics, home run per hit (HR/H) is the percentage of hits that are home runs. It is loosely related to isolated power, which is the ability to hit for extra-base hits, including home runs. Power hitters, players who readily hit many home runs tend to have higher HR/H than contact hitters. A player hitting 30 home runs and have 150 hits in a season would have HR/H of .200, while a player who hit 8 home runs and have 200 hits in a season would have H/HR of .040.
HR/H ratio has gotten higher over time. From 1959 to 2007, HR/H for leading power hitters in MLB was .3312, with the ratio being the highest from 1995 to 2001.

https://en.wikipedia.org/wiki/Presheaf%20with%20transfers | In algebraic geometry, a presheaf with transfers is, roughly, a presheaf that, like cohomology theory, comes with pushforwards, “transfer” maps. Precisely, it is, by definition, a contravariant additive functor from the category of finite correspondences (defined below) to the category of abelian groups (in category theory, “presheaf” is another term for a contravariant functor).
When a presheaf F with transfers is restricted to the subcategory of smooth separated schemes, it can be viewed as a presheaf on the category with extra maps , not coming from morphisms of schemes but also from finite correspondences from X to Y
A presheaf F with transfers is said to be -homotopy invariant if for every X.
For example, Chow groups as well as motivic cohomology groups form presheaves with transfers.
Finite correspondence
Let be algebraic schemes (i.e., separated and of finite type over a field) and suppose is smooth. Then an elementary correspondence is an irreducible closed subscheme , some connected component of X, such that the projection is finite and surjective. Let be the free abelian group generated by elementary correspondences from X to Y; elements of are then called finite correspondences.
The category of finite correspondences, denoted by , is the category where the objects are smooth algebraic schemes over a field; where a Hom set is given as:
and where the composition is defined as in intersection theory: given elementary correspondences from to and from to , their composition is:
where denotes the intersection product and , etc. Note that the category is an additive category since each Hom set is an abelian group.
This category contains the category of smooth algebraic schemes as a subcategory in the following sense: there is a faithful functor that sends an object to itself and a morphism to the graph of .
With the product of schemes taken as the monoid operation, the category is a symmetric monoidal category.
Sheaves with transfers
The basic notion underlying all of the different theories are presheaves with transfers. These are contravariant additive functorsand their associated category is typically denoted , or just if the underlying field is understood. Each of the categories in this section are abelian categories, hence they are suitable for doing homological algebra.
Etale sheaves with transfers
These are defined as presheaves with transfers such that the restriction to any scheme is an etale sheaf. That is, if is an etale cover, and is a presheaf with transfers, it is an Etale sheaf with transfers if the sequenceis exact and there is an isomorphismfor any fixed smooth schemes .
Nisnevich sheaves with transfers
There is a similar definition for Nisnevich sheaf with transfers, where the Etale topology is switched with the Nisnevich topology.
Examples
Units
The sheaf of units is a presheaf with transfers. Any correspondence induces a finite map of degree over , hence there is the induced m |
https://en.wikipedia.org/wiki/Correspondence%20%28algebraic%20geometry%29 | In algebraic geometry, a correspondence between algebraic varieties V and W is a subset R of V×W, that is closed in the Zariski topology. In set theory, a subset of a Cartesian product of two sets is called a binary relation or correspondence; thus, a correspondence here is a relation that is defined by algebraic equations. There are some important examples, even when V and W are algebraic curves: for example the Hecke operators of modular form theory may be considered as correspondences of modular curves.
However, the definition of a correspondence in algebraic geometry is not completely standard. For instance, Fulton, in his book on intersection theory, uses the definition above. In literature, however, a correspondence from a variety X to a variety Y is often taken to be a subset Z of X×Y such that Z is finite and surjective over each component of X. Note the asymmetry in this latter definition; which talks about a correspondence from X to Y rather than a correspondence between X and Y. The typical example of the latter kind of correspondence is the graph of a function f:X→Y. Correspondences also play an important role in the construction of motives (cf. presheaf with transfers).

https://en.wikipedia.org/wiki/Caroline%20M.%20Solomon | Caroline M. Solomon is an American academic whose teaching focuses on bringing deaf and hard-of-hearing students into the fields of science, technology, engineering, and mathematics. Having experienced first-hand the problems for deaf students in classrooms without sign language interpreters, Solomon, who teaches biology at Gallaudet University, has designed databases to help students and teachers network with organizations and interpreters familiar with educational bridges for deaf and hard-of-hearing students. She is a co-creator of a database that formalizes the lexicon of signs used for scientific and technological terms in American Sign Language. Her innovations to teaching techniques were recognized with the Ramón Margalef Award for Excellence in Education of the Association for the Sciences of Limnology and Oceanography in 2017.
Early life
Caroline Solomon grew up in Delaware and contracted spinal meningitis as an infant, which resulted in her being deaf in a hearing family. As a teenager, she participated in the Deaflympics as a swimmer and became interested in the environment because she was unable to swim in a heavily polluted creek near their home. Upon graduation from high school, she enrolled at Harvard University, studying both environmental science and public policy. When she entered Harvard, there were no sign language interpreters on the staff, but the university hired one midway through Solomon's first semester. She graduated with a Bachelor of Arts in 1996. Furthering her education, Solomon went on to earn a master's degree in biological oceanography from the University of Washington. Solomon earned her a PhD in biological oceanography from the University of Maryland in 2006.
Career
After completion of her master's, Solomon, who wanted to inspire other deaf and hard-of-hearing students, joined the faculty of Gallaudet University in 2000. She was promoted to full professor in 2011. Her research focuses on the ecological effects that occur when algae, bacteria, and viruses interact with nitrogen byproducts from agricultural production and other human activity. Studying waterways such as the Chesapeake Bay and the Anacostia River, she analyzes the occurrence of algal blooms and pollutants to determine prevention measures which can be implemented in conservation efforts.
Recognizing that her students are more visual than auditory, Solomon often demonstrates lessons in a visual way, such as lining up chairs to represent skin and having a student playing a pathogen try to break through. Working in tandem with the Anacostia Riverkeeper Project, the DC Water Research and Resources Institute, the Department of Energy and Environment, the Maryland Sea Grant College Program, and the National Science Foundation's Research Experiences for Undergraduates program, Solomon conducts summer research projects to help students not only learn how to research, but to understand the need to communicate their findings to create conservation policy. |

https://en.wikipedia.org/wiki/Lillian%20Pierce | Lillian Beatrix Pierce is a mathematician whose research connects number theory with harmonic analysis. She is a professor of mathematics at Duke University.
Early life and education
Pierce was home-schooled in Fallbrook, California and began playing the violin at age four. By age 11 she began performing professionally as a violinist. As a teenager, she also started taking classes at a local community college, accumulating so many units that some of the universities she applied to refused to consider her for freshman admission.
She entered Princeton University majoring in mathematics but intending to pursue an MD–PhD program;
under the influence of faculty mentor and undergraduate thesis supervisor Elias M. Stein, her interests shifted towards pure mathematics. As an undergraduate, she also became an intern at the National Security Agency.
She was Princeton's 2002 valedictorian and became a Rhodes Scholar, repeating two accomplishments of her brother Niles Pierce from nine years earlier.
She earned a master's degree at the University of Oxford in 2004. Returning to Princeton for doctoral study in mathematics, she completed her Ph.D. in 2009. Her dissertation, Discrete Analogues in Harmonic Analysis, was supervised by Stein.
Career
After postdoctoral studies with Roger Heath-Brown at Oxford and at the Hausdorff Center for Mathematics in Bonn, Germany, she became an assistant professor at Duke in 2014.
Research
Pierce was one of the first mathematicians to prove nontrivial upper bounds on the number of elements of finite order in an ideal class group.
Awards and honors
Pierce won the 2018 Sadosky Prize for research that "spans and connects a broad spectrum of problems ranging from character sums in number theory to singular integral operators in Euclidean spaces" including in particular "a polynomial Carleson theorem for manifolds". She received the 2019 Presidential Early Career Award for Scientists and Engineers. She was elected a Fellow of the American Mathematical Society in the class of 2021 "for contributions to number theory and harmonic analysis".

https://en.wikipedia.org/wiki/Semyon%20Belozyorov | Semyon Yefimovich Belozyorov (; 6 February 1904 — 1987) was a Soviet and Russian mathematician and a specialist in the field of history of mathematics. Professor, Candidate of Physical and Mathematical Sciences, Director of Rostov State University in 1938–1954.
Biography
Semyon Yefimovich Belozyorov was born on 6 February 1904. He studied at the Kulikovo village school in Kalachinsky District of Omsk Oblast. In his teens he worked as a shepherd in his home village. At the age of 18 he enrolled at Rabfak, and later graduated with honors from the Physics and Mathematics Faculty of Saratov State University and started to work there as teacher.
In 1938 he was appointed Director of Rostov State University and remained at this post in the most difficult years of the university. In 1939, under the leadership of Professor Mark Vygodsky he defended his thesis on the topic "From the history of the theory of functions of a complex variable". He was one of the first scientists in the Soviet Union to specialize in the field of history of mathematics (which was viewed ambiguously by the Soviet academic circles at that time), and specifically studied the history of the theory of analytic functions. He was the author of a number of scientific works and monographs: "The main stages in the development of the general theory of analytic functions" (1962), "Five famous problems of antiquity" (1975), etc.
He laid the foundations of a thorough study of the history of Saratov State University, and was the author of various publications on that topic. For many years he read a special lecture course "History and the modern theory of famous problems of antiquity" at Rostov State University.
He died in 1987.

https://en.wikipedia.org/wiki/Bonnie%20Gold | Bonnie Gold (born 1948) is an American mathematician, mathematical logician, philosopher of mathematics, and mathematics educator. She is a professor emerita of mathematics at Monmouth University.
Education and career
Gold completed her Ph.D. in 1976 at Cornell University, under the supervision of Michael D. Morley.
She was the chair of the mathematics department at Wabash College before moving to Monmouth, where she also became department chair.
Contributions
The research from Gold's dissertation, Compact and -compact formulas in ,
was later published in the journal Archiv für Mathematische Logik und Grundlagenforschung, and concerned infinitary logic.
With Sandra Z. Keith and William A. Marion she co-edited Assessment Practices in Undergraduate Mathematics, published by the Mathematical Association of America (MAA) in 1999.
With Roger A. Simons, Gold is also the editor of another book, Proof and Other Dilemmas: Mathematics and Philosophy (MAA, 2008).
Her essay "How your philosophy of mathematics impacts your teaching" was selected for inclusion in The Best Writing on Mathematics 2012. In it, she argues that the philosophy of mathematics affects the teaching of mathematics even when the teacher's philosophical principles are implicit and unexamined.
Recognition
In 2012, Gold became the winner of the 22nd Louise Hay Award of the Association for Women in Mathematics for her contributions to mathematics education. The award citation noted her work in educational assessment for undergraduate study in mathematics.

https://en.wikipedia.org/wiki/Tropical%20cryptography | In tropical analysis, tropical cryptography refers to the study of a class of cryptographic protocols built upon tropical algebras. In many cases, tropical cryptographic schemes have arisen from adapting classical (non-tropical) schemes to instead rely on tropical algebras. The case for the use of tropical algebras in cryptography rests on at least two key features of tropical mathematics: in the tropical world, there is no classical multiplication (a computationally expensive operation), and the problem of solving systems of tropical polynomial equations has been shown to be NP-hard.
Basic Definitions
The key mathematical object at the heart of tropical cryptography is the tropical semiring (also known as the min-plus algebra), or a generalization thereof. The operations are defined as follows for :
It is easily verified that with as the additive identity, these binary operations on form a semiring.

Definition
Let be a probability distribution and be a fixed natural number. Let be i.i.d. random variables with distribution , so for all .
Then the binomial process based on n and P is the random measure
where
Properties
Name
The name of a binomial process is derived from the fact that for all measurable sets the random variable follows a binomial distribution with parameters and :
Laplace-transform
The Laplace transform of a binomial process is given by
for all positive measurable functions .
Intensity measure
The intensity measure of a binomial process is given by
Generalizations
A generalization of binomial processes are mixed binomial processes. In these point processes, the number of points is not deterministic like it is with binomial processes, but is determined by a random variable . Therefore mixed binomial processes conditioned on are binomial process based on and .
