Der Satz von Stinespring, benannt nach , ist ein Satz aus dem mathematischen Teilgebiet der Funktionalanalysis aus dem Jahre 1955. Er besagt, dass vollständig positive Operatoren auf C*-Algebren im Wesentlichen Kompressionen von Hilbertraum-Darstellungen sind. (de)
In mathematics, Stinespring's dilation theorem, also called Stinespring's factorization theorem, named after W. Forrest Stinespring, is a result from operator theory that represents any completely positive map on a C*-algebra as a composition of two completely positive maps each of which has a special form: 1. * A *-representation of A on some auxiliary Hilbert space K followed by 2. * An operator map of the form T → V*TV. Moreover, Stinespring's theorem is a structure theorem from a C*-algebra into the algebra of bounded operators on a Hilbert space. Completely positive maps are shown to be simple modifications of *-representations, or sometimes called *-homomorphisms. (en)
