Oscillatory integral operator — In mathematics, in the field of harmonic analysis, an oscillatory integral operator is an integral operator of the form where the function is called the phase of the operator and the function is called the symbol of the operator. is a parameter.… … Wikipedia
Hilbert-Schmidt integral operator — In mathematics, a Hilbert Schmidt integral operator is a type of integral transform. Specifically, given a domain (an open and connected set) Omega; in n dimensional Euclidean space R n , a Hilbert Schmidt kernel is a function k : Omega; times;… … Wikipedia
Fourier integral operator — The concept of Fourier integral operators stems from mathematical analysis. They have become an important tool in the theory of partial differential equations. The class of Fourier integral Operators contains differential operators as well as… … Wikipedia
Operator (mathematics) — This article is about operators in mathematics. For other uses, see Operator (disambiguation). In basic mathematics, an operator is a symbol or function representing a mathematical operation. In terms of vector spaces, an operator is a mapping… … Wikipedia
Operator theory — In mathematics, operator theory is the branch of functional analysis that focuses on bounded linear operators, but which includes closed operators and nonlinear operators. Operator theory also includes the study of algebras of operators. Contents … Wikipedia
Integral Equations and Operator Theory — is a journal dedicated to operator theory and its applications to engineering and other mathematical sciences. As some approaches to the study of integral equations (theoretically and numerically) constitute a subfield of operator theory, the… … Wikipedia
Integral transform — In mathematics, an integral transform is any transform T of the following form:: (Tf)(u) = int {t 1}^{t 2} K(t, u), f(t), dt.The input of this transform is a function f , and the output is another function Tf . An integral transform is a… … Wikipedia
Integral — This article is about the concept of integrals in calculus. For the set of numbers, see integer. For other uses, see Integral (disambiguation). A definite integral of a function can be represented as the signed area of the region bounded by its… … Wikipedia
Integral equation — In mathematics, an integral equation is an equation in which an unknown function appears under an integral sign. There is a close connection between differential and integral equations, and some problems may be formulated either way. See, for… … Wikipedia
integral transform — In mathematics, a function that results when a given function is multiplied by a so called kernel function, and the product is integrated (see integration) between suitable limits. Its value lies in its ability to simplify intractable… … Universalium
