She was the third woman to become a mathematics professor in Australia, following Hanna Neumann and Cheryl Praeger. She was the author of several textbooks,
and her work on sum-free sets became a standard reference for its subject matter. She helped found several important organizations in combinatorics, developed a researcher network, and supported young students with interest in mathematics.
Early life and education
Street was born on 11 October 1932 in Melbourne, the daughter of a medical researcher. She earned a bachelor's degree in chemistry from the University of Melbourne in 1954, while working there as a tutor in chemistry and also studying mathematics. She finished a master's degree in chemistry at Melbourne in 1956. During this time she married another Melbourne chemist, Norman Street, and in 1957 the Streets and their young daughter moved to the University of Illinois at Urbana–Champaign where Norman Street had a new job.
At Illinois, Street took up mathematics again. After moving to Mildura and then returning to Urbana, she completed her doctorate at the University of Illinois in 1966, with a dissertation on group theory supervised by Michio Suzuki.
Career
After earning her doctorate, Street became a lecturer at the University of Queensland in 1967. While continuing to hold this position, she took a year of postdoctoral research at the University of Alberta, and on her return to Queensland in 1970 was promoted to senior lecturer, promoted again to reader in 1975, and given a personal chair as professor in 1985.
At Queensland, she directed the Centre for Discrete Mathematics and Computing from its formation in 1998 until 2004.
She has also held visiting positions at the University of Waterloo, University of Reading, University of Manitoba, University of Illinois at Urbana–Champaign, University of Western Australia, Auburn University, and University of Canterbury.
Service to mathematics
Street became the founding editor-in-chief of the Australasian Journal of Combinatorics in 1990, and continued to serve as editor-in-chief until 2001.
She helped found the Institute of Combinatorics and its Applications (ICA), became one of its founding fellows, and served as an editor of the Bulletin of the ICA from its founding in 1991 until 2014. She was president of the ICA from 1996 to 2002.
She was the founding president of the Combinatorial Mathematics Society of Australasia, for the 1997–1998 term.

https://en.wikipedia.org/wiki/Hopf%20decomposition | In mathematics, the Hopf decomposition, named after Eberhard Hopf, gives a canonical decomposition of a measure space (X, μ) with respect to an invertible non-singular transformation T:X→X, i.e. a transformation which with its inverse is measurable and carries null sets onto null sets. Up to null sets, X can be written as a disjoint union C ∐ D of T-invariant sets where the action of T on C is conservative and the action of T on D is dissipative. Thus, if τ is the automorphism of A = L∞(X) induced by T, there is a unique τ-invariant projection p in A such that pA is conservative and (I–p)A is dissipative.
Definitions
Wandering sets and dissipative actions. A measurable subset W of X is wandering if its characteristic function q = χW in A = L∞(X) satisfies qτn(q) = 0 for all n; thus, up to null sets, the translates Tn(W) are pairwise disjoint. An action is called dissipative if X = ∐ Tn(W) a.e. for some wandering set W.
Conservative actions. If X has no wandering subsets of positive measure, the action is said to be conservative.
Incompressible actions. An action is said to be incompressible if whenever a measurable subset Z satisfies T(Z) ⊆ Z then has measure zero. Thus if q = χZ and τ(q) ≤ q, then τ(q) = q a.e.
Recurrent actions. An action T is said to be recurrent if q ≤ τ(q) ∨ τ2(q) ∨ τ3(q) ∨ ... a.e. for any q = χY.
Infinitely recurrent actions. An action T is said to be infinitely recurrent if q ≤ τm (q) ∨ τm + 1(q) ∨ τm+2(q) ∨ ... a.e. for any q = χY and any m ≥ 1.
Recurrence theorem
Theorem. If T is an invertible transformation on a measure space (X,μ) preserving null sets, then the following conditions are equivalent on T (or its inverse):
T is conservative;
T is recurrent;
T is infinitely recurrent;
T is incompressible.
Since T is dissipative if and only if T−1 is dissipative, it follows that T is conservative if and only if T−1 is conservative.
If T is conservative, then r = q ∧ (τ(q) ∨ τ2(q) ∨ τ3(q) ∨ ⋅⋅⋅)⊥ = q ∧ τ(1 - q) ∧ τ2(1 -q) ∧ τ3(q) ∧ ... is wandering so that if q < 1, necessarily r = 0. Hence q ≤ τ(q) ∨ τ2(q) ∨ τ3(q) ∨ ⋅⋅⋅, so that T is recurrent.
If T is recurrent, then q ≤ τ(q) ∨ τ2(q) ∨ τ3(q) ∨ ⋅⋅⋅ Now assume by induction that q ≤ τk(q) ∨ τk+1(q) ∨ ⋅⋅⋅. Then τk(q) ≤ τk+1(q) ∨ τk+2(q) ∨ ⋅⋅⋅ ≤ . Hence q ≤ τk+1(q) ∨ τk+2(q) ∨ ⋅⋅⋅. So the result holds for k+1 and thus T is infinitely recurrent. Conversely by definition an infinitely recurrent transformation is recurrent.
Now suppose that T is recurrent. To show that T is incompressible it must be shown that, if τ(q) ≤ q, then τ(q) ≤ q. In fact in this case τn(q) is a decreasing sequence. But by recurrence, q ≤ τ(q) ∨ τ2(q) ∨ τ3(q) ∨ ⋅⋅⋅ , so q ≤ τ(q) and hence q = τ(q).
Finally suppose that T is incompressible. If T is not conservative there is a p ≠ 0 in A with the τn(p) disjoint (orthogonal). But then q = p ⊕ τ(p) ⊕ τ2(p) ⊕ ⋅⋅⋅ satisfies τ(q) < q with , contradicting incompressibility. So T is conservative.

https://en.wikipedia.org/wiki/Jantje%20Visscher | Jantje Visscher is an American mixed-media artist and teacher. Her work involves painting, printmaking, photography, and sculpture. Visscher uses geometry and mathematics to explore the dynamics of perception and optical effects through the use of nontraditional mixed media. She lives and works in Minneapolis, Minnesota, and is active in the Women's Art Resources of Minnesota Mentor Program and the Traffic Zone Center for Visual Art. Visscher is best known for hard-edge abstraction and minimalism within her scientific approach and exploration of perception and mathematics.
Early life and education
Jantje Visscher graduated with a Bachelor of Arts in Political Science from Antioch College in Yellow Springs, Ohio. She later earned her M.F.A in Fine Arts, Painting, and Printmaking from the University of California Berkeley in 1962. After graduate school, Visscher returned to Minnesota to take care of her family. In 1973, she connected to other female artists in Minnesota and helped found WARM.
Groups and Collectives
WARM (Women's Art Resource of Minnesota)
Visscher is one of the founding members of WARM, a feminist artist collective based in Minnesota. The collective became an important aspect of Visscher's practice and career She now serves as a mentor in WARM's Mentor Program, which pairs emerging artists with professional artists. Her philosophy as a mentor includes the constant revision of goals and refocusing one's daily life and artistic practices. She strives to help protegees develop basic career skills like marketing, drawing, and Photoshop, to help them become successful practicing artists. As a mentor, Visscher encourages philosophical discussion, the refinement of technical skills, and a regular schedule for creating art. Visscher mentored Maryellen Murphy from 2013 to 2014 as a part of the program, as well as Kate Vinson from 2015 to 2016, participating in the final capstone exhibitions associated with the program. She exhibited her piece, Capital in the final exhibition Landing and Launching in 2016, and exhibited Making Your Wings in the 2014 final exhibition Beyond the Surface.
Traffic Zone Center for Visual Art
Visscher is also one of the founding members of Traffic Zone Center for Visual Arts, which provides high-quality and affordable studio spaces for artists. Visscher has also exhibited her work through the Center, including in the 22nd Annual Spring Open Studio and a solo show, Motion, both in 2017. Motion featured collaged prints that display her fascination with the “constant motion of everything in the universe”.
Artistic Style
Visscher uses various techniques and processes to achieve nonobjective representations. Her style emerged by using geometric principles to create intuitive expression through repetition, limited color palettes, and grids. Visscher introduces a shifting relationship between figure and ground, as her experimental constructions invite various perceptions and illusions from viewers. Her work is r |

https://en.wikipedia.org/wiki/Ryu%E2%80%93Takayanagi%20conjecture | The Ryu–Takayanagi conjecture is a conjecture within holography that posits a quantitative relationship between the entanglement entropy of a conformal field theory and the geometry of an associated anti-de Sitter spacetime. The formula characterizes "holographic screens" in the bulk; that is, it specifies which regions of the bulk geometry are "responsible to particular information in the dual CFT". The conjecture is named after and , who jointly published the result in 2006. As a result, the authors were awarded the 2015 New Horizons in Physics Prize for "fundamental ideas about entropy in quantum field theory and quantum gravity". The formula was generalized to a covariant form in 2007.
Motivation
The thermodynamics of black holes suggests certain relationships between the entropy of black holes and their geometry. Specifically, the Bekenstein–Hawking area formula conjectures that the entropy of a black hole is proportional to its surface area:
The Bekenstein–Hawking entropy is a measure of the information lost to external observers due to the presence of the horizon. The horizon of the black hole acts as a "screen" distinguishing one region of the spacetime (in this case the exterior of the black hole) that is not affected by another region (in this case the interior). The Bekenstein–Hawking area law states that the area of this surface is proportional to the entropy of the information lost behind it.
The Bekenstein–Hawking entropy is a statement about the gravitational entropy of a system; however, there is another type of entropy that is important in quantum information theory, namely the entanglement (or von Neumann) entropy. This form of entropy provides a measure of how far from a pure state a given quantum state is, or, equivalently, how entangled it is. The entanglement entropy is a useful concept in many areas, such as in condensed matter physics and quantum many-body systems. Given its use, and its suggestive similarity to the Bekenstein–Hawking entropy, it is desirable to have a holographic description of entanglement entropy in terms of gravity.
Holographic preliminaries
The holographic principle states that gravitational theories in a given dimension are dual to a gauge theory in one lower dimension. The AdS/CFT correspondence is one example of such duality. Here, the field theory is defined on a fixed background and is equivalent to a quantum gravitational theory whose different states each correspond to a possible spacetime geometry. The conformal field theory is often viewed as living on the boundary of the higher dimensional space whose gravitational theory it defines. The result of such a duality is a dictionary between the two equivalent descriptions. For example, in a CFT defined on dimensional Minkowski space the vacuum state corresponds to pure AdS space, whereas the thermal state corresponds to a planar black hole. Important for the present discussion is that the thermal state of a CFT defined on the dimensiona |

In mathematics, Liouville–Bratu–Gelfand equation or Liouville's equation is a non-linear Poisson equation, named after the mathematicians Joseph Liouville, Gheorghe Bratu and Israel Gelfand. The equation reads
The equation appears in thermal runaway as Frank-Kamenetskii theory, astrophysics for example, Emden–Chandrasekhar equation. This equation also describes space charge of electricity around a glowing wire and describes planetary nebula.
Liouville's solution
In two dimension with Cartesian Coordinates , Joseph Liouville proposed a solution in 1853 as
where is an arbitrary analytic function with . In 1915, G.W. Walker found a solution by assuming a form for . If , then Walker's solution is
where is some finite radius. This solution decays at infinity for any , but becomes infinite at the origin for , becomes finite at the origin for and becomes zero at the origin for . Walker also proposed two more solutions in his 1915 paper.
Radially symmetric forms
If the system to be studied is radially symmetric, then the equation in dimension becomes
where is the distance from the origin. With the boundary conditions
and for , a real solution exists only for , where is the critical parameter called as Frank-Kamenetskii parameter. The critical parameter is for , for and for . For , two solution exists and for infinitely many solution exists with solutions oscillating about the point . For , the solution is unique and in these cases the critical parameter is given by .

https://en.wikipedia.org/wiki/Agust%C3%ADn%20Maravall | Agustín Maravall Herrero (born in 1944 in Madrid) is a Spanish economist. He is known for his contributions to the analysis of statistics and econometrics, particularly in seasonal adjustment and the estimation of signals in economic time series. He created a methodology and several computer programs for such analysis that are used throughout the world by analysts, researchers, and data producers. Maravall retired in December 2014 from the Bank of Spain.
Biography
Maravall spent his childhood in Paris, then moved to Madrid and finished secondary school at the Colegio Estudio. He completed a doctorate in agricultural engineering at the Technical University of Madrid, and worked for several years at the Spanish Ministry of Agriculture. With a Fulbright-Ford fellowship he came to the United States and completed a Ph.D. in Economics at the University of Wisconsin–Madison. In 1975, he moved to Washington, D.C. to work as a staff economist in the Research Division of the Federal Reserve Board of Governors. In 1979, he returned to Madrid as a senior economist in the Research Department of the Bank of Spain, and in 1989 he moved to Italy as Full Professor in the Department of Economics of the European University Institute in Florence. In 1996, he returned to the Bank of Spain as Chief Economist and Head of the Time Series Analysis Unit.
Maravall has been on the editorial board of multiple professional journals, including the Journal of Business and Economic Statistics and the Journal of Econometrics. He served on the Program and Scientific Committees of many international meetings and conferences. His teaching experience includes teaching courses in more than 30 countries to participants from more than 60 countries. He was Special Advisor to the European Central Bank and Eurostat, a member of the Board of Directors of the former Institute for Advanced Studies in the Social Sciences of Madrid, and a member of the High Advisory Council for R & D of the Generalitat Valenciana.
Research
Maravall's research focused on time series analysis, time series modeling, and time series applications to economic data. His key contribution, in collaboration with Victor Gómez was the creation of a model-based approach for jointly solving many statistical time series difficulties that affect the analysis and interpretation of economic time series. In the presence of potentially missing observations the typical (default) technique first performs automatic identification and forecasting of regression-ARIMA models (including adjustment for outliers and calendar effects). The model is then split into models for unobserved components (such as seasonal, trend, transient, and cyclical components), from which filters are generated to estimate and forecast the unobserved components. The model-based structure generates the estimators' joint distribution, from which parametric tests and inferences (such as the standard errors of all estimators and forecasts) can be obtained.

https://en.wikipedia.org/wiki/Hypercovering | In mathematics, and in particular homotopy theory, a hypercovering (or hypercover) is a simplicial object that generalises the Čech nerve of a cover. For the Čech nerve of an open cover one can show that if the space is compact and if every intersection of open sets in the cover is contractible, then one can contract these sets and get a simplicial set that is weakly equivalent to in a natural way. For the étale topology and other sites, these conditions fail. The idea of a hypercover is to instead of only working with -fold intersections of the sets of the given open cover , to allow the pairwise intersections of the sets in to be covered by an open cover , and to let the triple intersections of this cover to be covered by yet another open cover , and so on, iteratively. Hypercoverings have a central role in étale homotopy and other areas where homotopy theory is applied to algebraic geometry, such as motivic homotopy theory.
Formal definition
The original definition given for étale cohomology by Jean-Louis Verdier in SGA4, Expose V, Sec. 7, Thm. 7.4.1, to compute sheaf cohomology in arbitrary Grothendieck topologies. For the étale site the definition is the following:
Let be a scheme and consider the category of schemes étale over . A hypercover is a semisimplicial object of this category such that is an étale cover and such that is an étale cover for every .
Here, is the limit of the diagram which has one copy of for each -dimensional face of the standard -simplex (for ), one morphism for every inclusion of faces, and the augmentation map at the end. The morphisms are given by the boundary maps of the semisimplicial object .
Properties
The Verdier hypercovering theorem states that the abelian sheaf cohomology of an étale sheaf can be computed as a colimit of the cochain cohomologies over all hypercovers.
For a locally Noetherian scheme , the category of hypercoverings modulo simplicial homotopy is cofiltering, and thus gives a pro-object in the homotopy category of simplicial sets. The geometrical realisation of this is the Artin-Mazur homotopy type. A generalisation of E. Friedlander using bisimplicial hypercoverings of simplicial schemes is called the étale topological type.

He is recognized as the "Indiana Jones of Mathematics" for his work in polar climate modeling and has traveled to the polar regions eighteen times, in total, to study sea ice.
Biography
Golden first became interested in sea ice in his senior year of high school while working on a project studying passive microwave images of Antarctic sea ice at NASA Goddard Space Flight Center. He enrolled in Dartmouth College so that he could work at the Cold Regions Research and Engineering Laboratory with Stephen F. Ackley. He graduated from Dartmouth in 1980 with his bachelor's degree in mathematics and physics, and enrolled in the PhD program at the NYU Courant Institute of Mathematical Sciences. He received his PhD in 1984 and then worked as a National Science Foundation Postdoctoral Fellow in mathematical physics at Rutgers University and as an assistant professor of mathematics at Princeton University. He joined the Department of Mathematics at the University of Utah in 1991.
In 2012 he became one of the inaugural fellows of the American Mathematical Society. Golden's research focuses on modeling sea ice and its role in the climate system using theories of composite materials and statistical physics.

https://en.wikipedia.org/wiki/Rudolf%20Modley | Rudolf Modley (November 3, 1906 – September 28, 1976) was an Austrian-American research executive, graphic designer, management consultant and author, who founded Pictorial Statistics Inc. in 1934. He illustrated and wrote a series of books on pictorial statistics and pictorial symbolism.
Modley introduced and popularized the Isotype picture language in the United States, whereby he developed an own version of pictorial statistics. He also designed many pictorial symbols in the 1930s and 1940s, and worked on standardization of pictorial symbols.
Biography
Youth and studies
Modley was born in 1906 in Vienna, then the capital of the Austro-Hungarian Empire, to Alfred and Elsa (Hoffmann) Moddley. After regular education and high school, he studied at the University of Vienna, where he obtained his Doctor of Law degree in 1929. During his studies in Vienna Modley had been assistant to Otto Neurath in the Social Museum, which Neurath had founded in 1923 and directed ever since. Modley had got acquainted with Otto Neurath’s design philosophy, while still at high school, and since those days he had worked as volunteer for Neurath. In 1928 he got a part-time appointment as a staff member and instructor for foreign visitors at the museum.
Early career in the U.S.
In 1930 Modley came to the United States to do postgraduate work at the University of Chicago. Recommended by Neurath, he was appointed curator of Social Science at the Museum of Science and Industry in Chicago by Waldemar Kaempffert, a cousin of Neurath. By the end of 1931 Modley had to go back to Austria to obtain a permanent resident status, and returned in 1932.
In 1933 Modley had moved to New York, where he in 1934 he founded Pictorial Statistics Incorporated. The company promoted the production and distribution of ISOTYPE-like pictographs for education, news, and other forms of communications. The company was set up as "a non-profit organization that offered to draw charts, including Isotypes, for any editor or publisher interested in illustrating economic and social articles." Pictorial Statistics Inc. followed an independent course from Otto Neurath, who had set up an own institute, the Institute for Visual Education, to promote his ideas in the U.S. Modley also started working as consultant for several government agencies.
Later career in the U.S.
In the mid-1960s, Modley joined forces with cultural anthropologist Margaret Mead, jointly establishing an organization called Glyphs Inc., whose goal was to create a universal graphic symbol language to be understood by any members of culture, no matter how primitive. In his later years Modley was management consultant for several trade associations. Modley died in the Illinois Masonic Medical Center in Chicago in 1976.
Design Principles
In his monograph Pictographs and Graphs, Modley summarized his belief that a symbol should:
Follow principles of good design.
Be usable in either large or small sizes.

Tigers first silverware was the Midlands Counties Cup, Tigers entered this competition from 1881 to 1914. There were then no competitions until 1971 when the RFU Knockout Cup started. Tigers won this for the first time in 1979, the competition continued until 2005 when it was replaced by the Anglo-Welsh Cup which Tigers have won three times, a record since the re-launch and addition of Welsh sides. The league started in 1987 and Tigers were the inaugural champions of England, a play off for the title was introduced in 2003. Leicester hold the record for most Premiership titles (11), the most consecutive Premiership Final appearances (9) and the most Play off appearances (14). On 18 May 2008 against Gloucester at Kingsholm they were the first team to achieve an away semi-final victory in the Premiership play-offs. They were the first side to retain the Heineken Cup after winning the competition in 2001 and 2002.

https://en.wikipedia.org/wiki/Free%20product%20of%20associative%20algebras | In algebra, the free product (coproduct) of a family of associative algebras over a commutative ring R is the associative algebra over R that is, roughly, defined by the generators and the relations of the 's. The free product of two algebras A, B is denoted by A ∗ B. The notion is a ring-theoretic analog of a free product of groups.
In the category of commutative R-algebras, the free product of two algebras (in that category) is their tensor product.
Construction
We first define a free product of two algebras. Let A and B be algebras over a commutative ring R. Consider their tensor algebra, the direct sum of all possible finite tensor products of A, B; explicitly, where
We then set
where I is the two-sided ideal generated by elements of the form
We then verify the universal property of coproduct holds for this (this is straightforward.)
A finite free product is defined similarly.

https://en.wikipedia.org/wiki/Van%20der%20Corput%20inequality | In mathematics, the van der Corput inequality is a corollary of the Cauchy–Schwarz inequality that is useful in the study of correlations among vectors, and hence random variables. It is also useful in the study of equidistributed sequences, for example in the Weyl equidistribution estimate. Loosely stated, the van der Corput inequality asserts that if a unit vector in an inner product space is strongly correlated with many unit vectors , then many of the pairs must be strongly correlated with each other. Here, the notion of correlation is made precise by the inner product of the space : when the absolute value of is close to , then and are considered to be strongly correlated. (More generally, if the vectors involved are not unit vectors, then strong correlation means that .)
Statement of the inequality
Let be a real or complex inner product space with inner product and induced norm . Suppose that and that . Then
In terms of the correlation heuristic mentioned above, if is strongly correlated with many unit vectors , then the left-hand side of the inequality will be large, which then forces a significant proportion of the vectors to be strongly correlated with one another.
Proof of the inequality
We start by noticing that for any there exists (real or complex) such that and . Then,
since the inner product is bilinear
by the Cauchy–Schwarz inequality
by the definition of the induced norm
since is a unit vector and the inner product is bilinear

https://en.wikipedia.org/wiki/Confocal%20conic%20sections | In geometry, two conic sections are called confocal if they have the same foci.
Because ellipses and hyperbolas have two foci, there are confocal ellipses, confocal hyperbolas and confocal mixtures of ellipses and hyperbolas. In the mixture of confocal ellipses and hyperbolas, any ellipse intersects any hyperbola orthogonally (at right angles).
Parabolas have only one focus, so, by convention, confocal parabolas have the same focus and the same axis of symmetry. Consequently, any point not on the axis of symmetry lies on two confocal parabolas which intersect orthogonally (see below).
A circle is an ellipse with both foci coinciding at the center. Circles that share the same focus are called concentric circles, and they orthogonally intersect any line passing through that center.
The formal extension of the concept of confocal conics to surfaces leads to confocal quadrics.
Confocal ellipses and hyperbolas
Any hyperbola or (non-circular) ellipse has two foci, and any pair of distinct points in the Euclidean plane and any third point not on line connecting them uniquely determine an ellipse and hyperbola, with shared foci and intersecting orthogonally at the point (See and .)
The foci thus determine two pencils of confocal ellipses and hyperbolas.
By the principal axis theorem, the plane admits a Cartesian coordinate system with its origin at the midpoint between foci and its axes aligned with the axes of the confocal ellipses and hyperbolas. If is the linear eccentricity (half the distance between and then in this coordinate system
Each ellipse or hyperbola in the pencil is the locus of points satisfying the equation
with semi-major axis as parameter. If the semi-major axis is less than the linear eccentricity the equation defines a hyperbola, while if the semi-major axis is greater than the linear eccentricity it defines an ellipse.
Another common representation specifies a pencil of ellipses and hyperbolas confocal with a given ellipse of semi-major axis and semi-minor axis (so that each conic generated by choice of the parameter
If the conic is an ellipse. If the conic is a hyperbola. For there are no solutions. The common foci of every conic in the pencil are the points This representation generalizes naturally to higher dimensions (see ).
Limit curves
As the parameter approaches the value from below, the limit of the pencil of confocal ellipses degenerates to the line segment between foci on the -axis (an infinitely flat ellipse). As approaches from above, the limit of the pencil of confocal hyperbolas degenerates to the relative complement of that line segment with respect to the -axis; that is, to the two rays with endpoints at the foci pointed outward along the -axis (an infinitely flat hyperbola). These two limit curves have the two foci in common.
This property appears analogously in the 3-dimensional case, leading to the definition of the focal curves of confocal quadrics. See below.

https://en.wikipedia.org/wiki/Residual%20intersection | In algebraic geometry, the problem of residual intersection asks the following:
Given a subset Z in the intersection of varieties, understand the complement of Z in the intersection; i.e., the residual set to Z.
The intersection determines a class , the intersection product, in the Chow group of an ambient space and, in this situation, the problem is to understand the class, the residual class to Z:
where means the part supported on Z; classically the degree of the part supported on Z is called the equivalence of Z.
The two principal applications are the solutions to problems in enumerative geometry (e.g., Steiner's conic problem) and the derivation of the multiple-point formula, the formula allowing one to count or enumerate the points in a fiber even when they are infinitesimally close.
The problem of residual intersection goes back to the 19th century. The modern formulation of the problems and the solutions is due to Fulton and MacPherson. To be precise, they develop the intersection theory by a way of solving the problems of residual intersections (namely, by the use of the Segre class of a normal cone to an intersection.) A generalization to a situation where the assumption on regular embedding is weakened is due to .
Definition
The following definition is due to .
Let

where is the projectivization (in the classical sense) and is the ideal sheaf defining .
Note: if is the blow-up of along , then, for , the surjection gives the closed embedding:
,
which is the isomorphism if the inclusion is a regular embedding.
If the are scheme-theoretic connected components of , then
For example, if Y is the projective space, then Bézout's theorem says the degree of is and so the above is a different way to count the contributions to the degree of the intersection. In fact, in applications, one combines Bézout's theorem.
Let be regular embeddings of schemes, separated and of finite type over the base field; for example, this is the case if Xi are effective Cartier divisors (e.g., hypersurfaces). The intersection product of

Formulae
Quillen's excess-intersection formula
The formula in the topological setting is due to .
Now, suppose we are given Y{{}} → Y and suppose i: X = X ×Y Y → Y is regular of codimension d so that one can define i! as before. Let F be the excess bundle of i and i'; that is, it is the pullback to X{{}} of the quotient of N by the normal bundle of i. Let e(F) be the Euler class (top Chern class) of F, which we view as a homomorphism from Ak−d (X{{}}) to Ak−d(X{{}}). Then
where i! is determined by the morphism Y{{}} → Y → Y.

https://en.wikipedia.org/wiki/Multivariate%20Laplace%20distribution | In the mathematical theory of probability, multivariate Laplace distributions are extensions of the Laplace distribution and the asymmetric Laplace distribution to multiple variables. The marginal distributions of symmetric multivariate Laplace distribution variables are Laplace distributions. The marginal distributions of asymmetric multivariate Laplace distribution variables are asymmetric Laplace distributions.
Symmetric multivariate Laplace distribution
A typical characterization of the symmetric multivariate Laplace distribution has the characteristic function:
where is the vector of means for each variable and is the covariance matrix.
Unlike the multivariate normal distribution, even if the covariance matrix has zero covariance and correlation the variables are not independent. The symmetric multivariate Laplace distribution is elliptical.
Probability density function
If , the probability density function (pdf) for a k-dimensional multivariate Laplace distribution becomes:

In the correlated bivariate case, i.e., k = 2, with the pdf reduces to:

For the uncorrelated bivariate Laplace case, that is k = 2, and , the pdf becomes:
Asymmetric multivariate Laplace distribution
A typical characterization of the asymmetric multivariate Laplace distribution has the characteristic function:
As with the symmetric multivariate Laplace distribution, the asymmetric multivariate Laplace distribution has mean , but the covariance becomes . The asymmetric multivariate Laplace distribution is not elliptical unless , in which case the distribution reduces to the symmetric multivariate Laplace distribution with .
The probability density function (pdf) for a k-dimensional asymmetric multivariate Laplace distribution is:
where:
and is the modified Bessel function of the second kind.
The asymmetric Laplace distribution, including the special case of , is an example of a geometric stable distribution. It represents the limiting distribution for a sum of independent, identically distributed random variables with finite variance and covariance where the number of elements to be summed is itself an independent random variable distributed according to a geometric distribution. Such geometric sums can arise in practical applications within biology, economics and insurance. The distribution may also be applicable in broader situations to model multivariate data with heavier tails than a normal distribution but finite moments.
The relationship between the exponential distribution and the Laplace distribution allows for a simple method for simulating bivariate asymmetric Laplace variables (including for the case of ).

https://en.wikipedia.org/wiki/Subspace%20identification%20method | In mathematics, specifically in control theory, subspace identification (SID) aims at identifying linear time invariant (LTI) state space models from input-output data. SID does not require that the user parametrizes the system matrices before solving a parametric optimization problem and, as a consequence, SID methods do not suffer from problems related to local minima that often lead to unsatisfactory identification results.
History
SID methods are rooted in the work by the German mathematician Leopold Kronecker (1823–1891). Kronecker showed that a power series can be written as a rational function when the rank of the Hankel operator that has the power series as its symbol is finite. The rank determines the order of the polynomials of the rational function.
In the 1960s the work of Kronecker inspired a number of researchers in the area of Systems and Control, like Ho and Kalman, Silverman and Youla and Tissi, to store the Markov parameters of an LTI system into a finite dimensional Hankel matrix and derive from this matrix an (A,B,C) realization of the LTI system. The key observation was that when the Hankel matrix is properly dimensioned versus the order of the LTI system, the rank of the Hankel matrix is the order of the LTI system and the SVD of the Hankel matrix provides a basis of the column space observability matrix and row space of the controllability matrix of the LTI system. Knowledge of this key spaces allows to estimate the system matrices via linear least squares.
An extension to the stochastic realization problem where we have knowledge only of the Auto-correlation (covariance) function of the output of an LTI system driven by white noise, was derived by researchers like Akaike.
A second generation of SID methods attempted to make SID methods directly operate on input-output measurements of the LTI system in the decade 1985–1995. One such generalization was presented under the name of the Eigensystem Realization Algorithm (ERA) made use of specific input-output measurements considering the impulse inputs. It has been used for modal analysis of flexible structures, like bridges, space structures, etc. These methods have demonstrated to work in practice for resonant structures they did not work well for other type of systems and an input different from an impulse. A new impulse to the development of SID methods was made for operating directly on generic input-output data and avoiding to first explicitly compute the Markov parameters or estimating the samples of covariance functions prior to realizing the system matrices. Pioneers that contributed to these breakthroughs were Van Overschee and De Moor – introducing the N4SID approach, Verhaegen – introducing the MOESP approach and Larimore – presenting ST in the framework of Canonical Variate Analysis (CVA)

https://en.wikipedia.org/wiki/Analysis%20of%20Boolean%20functions | In mathematics and theoretical computer science, analysis of Boolean functions is the study of real-valued functions on or (such functions are sometimes known as pseudo-Boolean functions) from a spectral perspective. The functions studied are often, but not always, Boolean-valued, making them Boolean functions. The area has found many applications in combinatorics, social choice theory, random graphs, and theoretical computer science, especially in hardness of approximation, property testing, and PAC learning.
Basic concepts
We will mostly consider functions defined on the domain . Sometimes it is more convenient to work with the domain instead. If is defined on , then the corresponding function defined on is
Similarly, for us a Boolean function is a -valued function, though often it is more convenient to consider -valued functions instead.
Fourier expansion
Every real-valued function has a unique expansion as a multilinear polynomial:
(Note that even if the function is 0-1 valued this is not a sum mod 2, but just an ordinary sum of real numbers.)
This is the Hadamard transform of the function , which is the Fourier transform in the group . The coefficients are known as Fourier coefficients, and the entire sum is known as the Fourier expansion of . The functions are known as Fourier characters, and they form an orthonormal basis for the space of all functions over , with respect to the inner product .
The Fourier coefficients can be calculated using an inner product:
In particular, this shows that , where the expected value is taken with respect to the uniform distribution over . Parseval's identity states that
If we skip , then we get the variance of :
Fourier degree and Fourier levels
The degree of a function is the maximum such that for some set of size . In other words, the degree of is its degree as a multilinear polynomial.
It is convenient to decompose the Fourier expansion into levels: the Fourier coefficient is on level .
The degree part of is
It is obtained from by zeroing out all Fourier coefficients not on level .
We similarly define .
Influence
The 'th influence of a function can be defined in two equivalent ways:
If is Boolean then is the probability that flipping the 'th coordinate flips the value of the function:
If then doesn't depend on the 'th coordinate.
The total influence of is the sum of all of its influences:
The total influence of a Boolean function is also the average sensitivity of the function. The sensitivity of a Boolean function at a given point is the number of coordinates such that if we flip the 'th coordinate, the value of the function changes. The average value of this quantity is exactly the total influence.
The total influence can also be defined using the discrete Laplacian of the Hamming graph, suitably normalized: .
A generalized form of influence is the -stable influence, defined by:

The lemma was developed and named after the mathematician Yiannis N. Moschovakis.
The lemma may be expressed generally as follows:
Let be a non-selfdual pointclass closed under real quantification and , and a -well-founded relation on of rank . Let be such that . Then there is a -set which is a choice set for R , that is:

https://en.wikipedia.org/wiki/Lp%20sum | {{DISPLAYTITLE:Lp sum}}
In mathematics, and specifically in functional analysis, the Lp sum of a family of Banach spaces is a way of turning a subset of the product set of the members of the family into a Banach space in its own right. The construction is motivated by the classical Lp spaces.
Definition
Let be a family of Banach spaces, where may have arbitrarily large cardinality. Set
the product vector space.
The index set becomes a measure space when endowed with its counting measure (which we shall denote by ), and each element induces a function
Thus, we may define a function
and we then set
together with the norm
The result is a normed Banach space, and this is precisely the Lp sum of
Properties
Whenever infinitely many of the contain a nonzero element, the topology induced by the above norm is strictly in between product and box topology.
Whenever infinitely many of the contain a nonzero element, the Lp sum is neither a product nor a coproduct.

https://en.wikipedia.org/wiki/Olga%20Tsuberbiller | Olga Tsuberbiller (, - 28 September 1975) was a Russian mathematician noted for her creation of the textbook Problems and Exercises in Analytic Geometry. The book has been used as a standard text for high schools since its creation in 1927. Sophia Parnok, noted Russian poet dedicated her verses in the Half-voiced cycle to Tsuberbiller, and the educator cared for Parnok during her final illness, later becoming her literary executor. She later became the partner of the noted opera singer, Concordia Antarova. Tsuberbiller was designated as an Honored Scientist of the Russian Soviet Federative Socialist Republic in 1955.
Early life
Olga Nikolaevna Gubonina () was born on 7 September 1885 in Moscow to Nadezhda Konstantinovna Artyukhova () and Nikolai Petrovich Gubonin (). Her mother was engaged in farming and her father was employed by the Chinese Eastern Railway. She was the granddaughter of the industrialist and spent at least part of her youth on the family's estate at Gurzuf. The resort, which now makes up Gurzuf was founded by Gubonina's grandfather and uncle, Sergei Gubonin (). The two designed the 93 hotels and summer cottages with the assistance of the architect Platon Konstantinovich Terebenev () and it quickly became a favorite place of writers, as it had been in earlier years for Alexander Pushkin. Her older brother, Pyotr Nikolaevich, namesake of both her grandfather and father, was in the Russian Navy and wounded at the Battle of Chemulpo Bay during the Russo-Japanese War and went on to serve in World War I. Little is known of her childhood, but she graduated from the Bestuzhev Courses in 1908.
Career
Gubonina immediately began teaching analytical geometry in the Bestuzhev Courses under the direction of B. K. Mlodzievsky. At some point she married and was widowed during the Russian Civil War, thereafter going by the surname Tsuberbiller. Tsuberbiller was dedicated to her students' education, establishing both a mathematics library and reading room to facilitate further study. She counseled and tutored students and worked to popularize the study of math, while she was working in the women's courses. In the 1920s, she began teaching at the First Moscow State University. At the beginning of 1923, Tsuberbiller met and became friends with Sophia Parnok. The exact nature of her relationship with Parnok is unknown as, while she occupied a significant place in the poet's life, Parnok did not describe Tsuberbiller in the same sexual context as her lovers. Instead, Tsuberbiller was a protector, as expressed in the poem cycle Half-voiced, which describes Tsuberbiller as a type of guardian angel. By 1925, she had become Parnok's closest friend, and when Parnok's lover Lyudmila Vladimirovna Erarskaya was hospitalized for a mental break, Tsuberbiller was the one to whom Parnok turned to regain her equilibrium. The following year, Parnok moved in with Tsuberbiller on Neopalimovsky Lane at Smolensky Boulevard, though Tsuberbiller was already overwork |

https://en.wikipedia.org/wiki/James%20Clerk%20Maxwell%20Foundation | The James Clerk Maxwell Foundation is a registered Scottish charity set up in 1977. By supporting physics and mathematics, it honors one of the greatest physicists, James Clerk Maxwell (1831–1879), and while attempting to increase the public awareness and trust of science. It maintains a small museum in Maxwell's birthplace. This museum is owned by the Foundation.
Purpose
The James Clerk Maxwell Foundation aims to increase the public awareness of the many scientific advances made by Maxwell over his lifetime and to highlight their importance in the world today. It summarizes Maxwell's many innovative technical advances and displays, in Maxwell’s birthplace, the history of Maxwell's family. The Foundation awards grants and prizes and supports mathematical challenges designed to encourage young students to study as mathematicians, scientists and engineers and become leaders in the world.
History
The James Clerk Maxwell Foundation was formed in 1977 by the late Sydney Ross, Professor of Colloidal chemistry at Rensselaer Polytechnic Institute in New York, USA. Ross was born in Scotland and he inherited monies from his late father’s whisky business, Ross, Campbell Ltd.
In 1993, the Foundation acquired 14 India Street, Edinburgh, the birthplace of Maxwell.
Since 1993, the house has been refurbished to its original standard and a small museum has been developed which features Maxwell’s family, life and scientific advances. These have resulted in Maxwell now being recognised as the most famous scientist in the era between Newton and Einstein.
Maxwell's birthplace
Maxwell was born at 14 India Street on 13 June 1831. This four-floor townhouse has 3–4 rooms on each floor. The Foundation lets the basement and top floor to tenants and maintains on the ground and first floor a modest museum which can be opened for visits by prior appointment.
Maxwell’s father, John Clerk Maxwell of Middlebie, had previously inherited land at Corsock in Galloway and he divided his time between Galloway and his 1820s townhouse in Edinburgh’s New Town. In 1830, John Clerk Maxwell commenced building a new house on his Corsock farm and would later name this Glenlair House. The Clerk Maxwell family moved permanently to Glenlair when James was two years old. Maxwell’s mother died when he was only eight years old and, two years later, he returned to Edinburgh to attend school at the Edinburgh Academy.
Maxwell studied at the University of Edinburgh and the University of Cambridge and his career followed professorial appointments at Marischal College Aberdeen, King's College London and the University of Cambridge. While in Aberdeen, Maxwell married the College Principal’s daughter Katherine Dewar.

https://en.wikipedia.org/wiki/Ovidio%20Montalbani | Ovidio Montalbani (18 November 1601 – 20 September 1671), also known by his pseudonym Giovanni Antonio Bumaldi, was an Italian polymath. He was a professor of logic, mathematics, astronomy, and medicine at the University of Bologna.
Life
Ovidio Montalbani studied philosophy with Vincenzo Montecalvi and medicine with the famous physician Bartolomeo Ambrosini. In 1625 at a very young age he became a lector at the University of Bologna, teaching first logic, then the theoretic medicine, mathematics and astronomy and later moral philosophy. In 1657, he became custodian of the Aldrovandi Museum - succeeding Bartolomeo Ambrosini, who had been custodian since 1642. He was the doyen of the Collegio Medico of Bologna and its prior from 1664 onwards.
Montalbani was a member of several academies, including the Accademia dei Gelati (with the alias "l'Innestato"), the Accademia degli Indomiti (as "lo Stellato"), and the Accademia della Notte (as "il Rugiadoso"). He was also a member of the free-thinking Venetian Accademia degli Incogniti, as well as one of the founders of the Accademia dei Vespertini, which held its first Assemblies in his house.
A politically involved citizen of the city of Bologna, he held several magistrates, such as those of the court of the merchant forum and Tribune of the Plebs. As a censor for the Bolognese Inquisition he was charged of reviewing the first edition of Galileo’s Complete Works, published in Bologna by Carlo Manolessi, in 1655–1656.
He died in Bologna on 20 September 1671.
Works
Ovidio Montalbani was one of the most prolific polymaths of his day. Among his many publications can be found works on archaeology, linguistics, medicine and botany. In 1629 he was given the task of writing the Tacuino, a sort of annually produced astrological calendar for doctors indicating the best and worst days for blood-letting, purges and surgery. Montalbani often enriched this medical «almanac» with essays on subjects as diverse as the grafting of plants and the Bolognese and Lombard dialects. Montalbani's tacuinum of 1661, entitled, Antineotiologia, an attack on innovations in the practice of medicine, was harshly criticized by Marcello Malpighi and Giovanni Alfonso Borelli.
In his “De Illuminabili Lapide Bononiensi Epistola” (1634), Montalbani discussed the properties of the “Bologna stone” a piece of barium sulfate (baryte) found on Mount Paderno. Montalbani's treatise was one of the first studies on the subject of inorganic phosphorescence. In 1668 Montalbani edited the previously unprinted Dendrologia by Ulisse Aldrovandi.
Montalbani published a number of scientific works under the pseudonym of Giovanni Antonio Bumaldi. Carl Peter Thunberg gave the name of Bumalda to a genus of Japanese plants.
A close friend of Thomas Dempster, he pronounced his funeral oration, which was published in Bologna in 1626, a year after Dempster's death.
Montalbani is an ambivalent figure in the early seventeenth-century Scientific Revolution. W |

https://en.wikipedia.org/wiki/Discrete-time%20proportional%20hazards | Hazard rate models are widely used to model duration data in a wide range
of disciplines, from bio-statistics to economics.
Grouped duration data are widespread in many applications. Unemployment durations are typically measured over weeks or months and these time intervals may be considered too large for continuous approximations to hold. In this case, we will typically have grouping points , where . Models allow for time-invariant and time-variant covariates, but the latter require stronger assumptions in terms of exogeneity. The discrete-time hazard function can be written as:
where is the survivor function. It can be shown that this can be rewritten as:
These probabilities provide the building blocks for setting up the Likelihood function, which ends up being:
This maximum likelihood maximization depends on the specification of the baseline hazard functions. These specifications include fully parametric models, piece-wise-constant proportional hazard models, or partial likelihood approaches that estimate the baseline hazard as a nuisance function. Alternatively, one can be more flexible for the baseline hazard and impose more structure for This approach performs well for certain measures and can approximate arbitrary hazard functions relatively well, while not imposing stringent computational requirements. When the covariates are omitted from the analysis, the maximum likelihood boils down to the Kaplan-Meier estimator of the survivor function.
Another way to model discrete duration data is to model transitions using binary choice models.

https://en.wikipedia.org/wiki/Multivalued%20treatment | In statistics, in particular in the design of experiments, a multi-valued treatment is a treatment that can take on more than two values. It is related to the dose-response model in the medical literature.
Description
Generally speaking, treatment levels may be finite or infinite as well as ordinal or cardinal, which leads to a large collection of possible treatment effects to be studied in applications. One example is the effect of different levels of program participation (e.g. full-time and part-time) in a job training program.
Assume there exists a finite collection of multi-valued treatment status with J some fixed integer. As in the potential outcomes framework, denote the collection of potential outcomes under the treatment J, and denotes the observed outcome and is an indicator that equals 1 when the treatment equals j and 0 when it does not equal j, leading to a fundamental problem of causal inference. A general framework that analyzes ordered choice models in terms of marginal treatment effects and average treatment effects has been extensively discussed by Heckman and Vytlacil.
Recent work in the econometrics and statistics literature has focused on estimation and inference for multivalued treatments and ignorability conditions for identifying the treatment effects. In the context of program evaluation, the propensity score has been generalized to allow for multi-valued treatments, while other work has also focused on the role of the conditional mean independence assumption. Other recent work has focused more on the large sample properties of an estimator of the marginal mean treatment effect conditional on a treatment level in the context of a difference-in-differences model, and on the efficient estimation of multi-valued treatment effects in a semiparametric framework.

https://en.wikipedia.org/wiki/Optimal%20instruments | In statistics and econometrics, optimal instruments are a technique for improving the efficiency of estimators in conditional moment models, a class of semiparametric models that generate conditional expectation functions. To estimate parameters of a conditional moment model, the statistician can derive an expectation function (defining "moment conditions") and use the generalized method of moments (GMM). However, there are infinitely many moment conditions that can be generated from a single model; optimal instruments provide the most efficient moment conditions.
As an example, consider the nonlinear regression model
where is a scalar (one-dimensional) random variable, is a random vector with dimension , and is a -dimensional parameter. The conditional moment restriction is consistent with infinitely many moment conditions. For example:
More generally, for any vector-valued function of , it will be the case that
.
That is, defines a finite set of orthogonality conditions.
A natural question to ask, then, is whether an asymptotically efficient set of conditions is available, in the sense that no other set of conditions achieves lower asymptotic variance. Both econometricians and statisticians have extensively studied this subject.
The answer to this question is generally that this finite set exists and have been proven for a wide range of estimators. Takeshi Amemiya was one of the first to work on this problem and show the optimal number of instruments for nonlinear simultaneous equation models with homoskedastic and serially uncorrelated errors. The form of the optimal instruments was characterized by Lars Peter Hansen, and results for nonparametric estimation of optimal instruments are provided by Newey. A result for nearest neighbor estimators was provided by Robinson.
In linear regression
The technique of optimal instruments can be used to show that, in a conditional moment linear regression model with iid data, the optimal GMM estimator is generalized least squares. Consider the model
where is a scalar random variable, is a -dimensional random vector, and is a -dimensional parameter vector. As above, the moment conditions are
where is an instrument set of dimension (). The task is to choose to minimize the asymptotic variance of the resulting GMM estimator. If the data are iid, the asymptotic variance of the GMM estimator is
where .
The optimal instruments are given by
which produces the asymptotic variance matrix
These are the optimal instruments because for any other , the matrix
is positive semidefinite.
Given iid data , the GMM estimator corresponding to is
which is the generalized least squares estimator. (It is unfeasible because is unknown.)
