  • Dilation (operator theory) — In operator theory, a dilation of an operator T on a Hilbert space H is an operator on a larger Hilbert space K , whose restriction to H is T. More formally, let T be a bounded operator on some Hilbert space H, and H be a subspace of a larger… …   Wikipedia

  • Dilation (morphology) — Dilation is one of the basic operations in mathematical morphology. Originally developed for binary images, it has been expanded first to grayscale images, and then to complete lattices. The dilation operation usually uses a structuring element… …   Wikipedia

  • Dilation — (or dilatation) refers to an enlargement or expansion in bulk or extent, the opposite of contraction. It derives from the Latin dilatare, to spread wide . In physiology: Pupillary dilation, dilation of the pupil of the eye Cervical dilation, the… …   Wikipedia

  • Dilation (mathematics) — In mathematics, a dilation is a function fnof; from a metric space into itself that satisfies the identity:d(f(x),f(y))=rd(x,y) ,for all points x , y , where d ( x , y ) is the distance from x to y and r is some positive real number. In Euclidean …   Wikipedia

  • Dilation (metric space) — In mathematics, a dilation is a function f from a metric space into itself that satisfies the identity for all points (x,y) where d(x,y) is the distance from x to y and r is some positive real number. In Euclidean space, such a dilation is a… …   Wikipedia

  • Naimark's dilation theorem — In operator theory, Naimark s dilation theorem is a result that characterizes positive operator valued measures. It can be viewed as a consequence of Stinespring s dilation theorem. Contents 1 Note 2 Some preliminary notions 3 Naimark s theorem …   Wikipedia

  • Sz.-Nagy's dilation theorem — The Sz. Nagy dilation theorem (proved by Béla Szőkefalvi Nagy) states that every contraction T on a Hilbert space H has a unitary dilation U to a Hilbert space K , containing H , with:T^n = P H U^n vert HMoreover, such a dilation is unique (up to …   Wikipedia

  • Subnormal operator — In mathematics, especially operator theory, subnormal operators are bounded operators on a Hilbert space defined by weakening the requirements for normal operators. Some examples of subnormal operators are isometries and Toeplitz operators with… …   Wikipedia

  • Shift operator — In mathematics, and in particular functional analysis, the shift operators are examples of linear operators, important for their simplicity and natural occurrence. They are used in diverse areas, such as Hardy spaces, the theory of abelian… …   Wikipedia

  • Refinable function — In mathematics, in the area of wavelet analysis, a refinable function is a function which fulfills some kind of self similarity. A function varphi is called refinable with respect to the mask h if:varphi(x)=2cdotsum {k=0}^{N 1} h… …   Wikipedia
