Krein–Milman theorem — In mathematics, more precisely in functional analysis, the Krein–Milman theorem is a statement about convex sets. A particular case of this theorem, which can be easily visualized, states that given a convex polygon, one only needs the corners of … Wikipedia
Tannaka–Krein duality — In mathematics, Tannaka–Krein duality theory concerns the interaction of a compact topological group and its category of linear representations. Its natural extension to the non Abelian case is the Grothendieck duality theory. It extends an… … Wikipedia
Tannaka-Krein duality — In mathematics, Tannaka Krein duality theory concerns the interaction of a compact topological group and its category of linear representations. It extends an important mathematical duality between compact and discrete commutative topological… … Wikipedia

Mark Grigoryevich Krein — Mark Grigorievich Krein ( ru. Марк Григорьевич Крейн; 3 April 1907 – 17 October 1989) was a Soviet Jewish mathematician, one of the major figures of the Soviet school of functional analysis. He is known for works in operator theory (in close… … Wikipedia
Gelfand–Naimark theorem — In mathematics, the Gelfand–Naimark theorem states that an arbitrary C* algebra A is isometrically * isomorphic to a C* algebra of bounded operators on a Hilbert space. This result was a significant point in the development of the theory of C*… … Wikipedia
Perron–Frobenius theorem — In linear algebra, the Perron–Frobenius theorem, proved by Oskar Perron (1907) and Georg Frobenius (1912), asserts that a real square matrix with positive entries has a unique largest real eigenvalue and that the corresponding… … Wikipedia
Riesz–Thorin theorem — In mathematics, the Riesz–Thorin theorem, often referred to as the Riesz–Thorin interpolation theorem or the Riesz–Thorin convexity theorem is a result about interpolation of operators. It is named after Marcel Riesz and his student G. Olof… … Wikipedia
de Finetti's theorem — In probability theory, de Finetti s theorem explains why exchangeable observations are conditionally independent given some latent variable to which an epistemic probability distribution would then be assigned. It is named in honor of Bruno de… … Wikipedia
Stone–Weierstrass theorem — In mathematical analysis, the Weierstrass approximation theorem states that every continuous function defined on an interval [ a , b ] can be uniformly approximated as closely as desired by a polynomial function. Because polynomials are the… … Wikipedia
M. Riesz extension theorem — The M. Riesz extension theorem is a theorem in mathematics, proved by Marcel Riesz during his study of the problem of moments.FormulationLet E be a real vector space, F subset E be a vector subspace, and let K subset E be a convex cone.Then, a… … Wikipedia
