Approximation property — In mathematics, a Banach space is said to have the approximation property (AP in short), if every compact operator is a limit of finite rank operators. The converse is always true.Every Hilbert space has this property. There are, however, Banach… … Wikipedia
Approximation in algebraic groups — In mathematics, strong approximation in linear algebraic groups is an important arithmetic property of matrix groups. In rough terms, it explains to what extent there can be an extension of the Chinese remainder theorem to various kinds of… … Wikipedia
Approximation theory — In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby. Note that what is meant by best and simpler will depend on … Wikipedia
Haagerup property — In mathematics, the Haagerup property, also known as Gromov s a T menability, is a property of groups that is a strong negation of Kazhdan s property (T). Property (T) is considered a representation theoretic form of rigidity, so the Haagerup… … Wikipedia
K-approximation of k-hitting set — In computer science, k approximation of k hitting set is an approximation algorithm for weighted hitting set. The input is a collection S of subsets of some universe T and a mapping W from S to non negative numbers called the weights of the… … Wikipedia
Relaxation (approximation) — In mathematical optimization and related fields, relaxation is a modeling strategy. A relaxation is an approximation of a difficult problem by a nearby problem that is easier to solve. A solution of the relaxed problem provides information about… … Wikipedia
Kazhdan's property (T) — In mathematics, a locally compact topological group G has property (T) if the trivial representation is an isolated point in its unitary dual equipped with the Fell topology. Informally, this means that if G acts unitarily on a Hilbert space and… … Wikipedia
Asymptotic equipartition property — In information theory the asymptotic equipartition property (AEP) is a general property of the output samples of a stochastic source. It is fundamental to the concept of typical set used in theories of compression.Roughly speaking, the theorem… … Wikipedia
Sparse approximation — is the problem of finding a signal or vector estimate with sparseness property, that is having a small number of nonzero elements, that satisfies (approximately) a system of equations.For example, consider a linear system of equations y = Ax ,… … Wikipedia
equitable approximation doctrine — The principle applied in a few cases whereby a testamentary gift is saved from defeat by the rule against perpetuities by the contrived reasoning that the intent of the testator was that the donee should have the property and that the time of… … Ballentine's law dictionary
