87Banachalgebra — Banachalgebren (nach Stefan Banach) sind mathematische Objekte der Funktionalanalysis, die einige bekannte Funktionenräume und Operatorenalgebren anhand wesentlicher gemeinsamer Eigenschaften verallgemeinern, z. B. Räume stetiger oder… …
88H*-Algebra — Eine H* Algebra ist eine mathematische Struktur, die im mathematischen Teilgebiet der Funktionalanalysis untersucht wird. Es handelt sich um eine involutive Banachalgebra, die gleichzeitig ein Hilbertraum ist, zusammen mit einer Bedingung, die… …
89Evenness of zero — The number 0 is even. There are several ways to determine whether an integer is even or odd, all of which indicate that 0 is an even number: it is a multiple of 2, it is evenly divisible by 2, it is surrounded on both sides by odd integers, and… …
90Triple system — In algebra, a triple system is a vector space V over a field F together with a F trilinear map: (cdot,cdot,cdot) colon V imes V imes V o V.The most important examples are Lie triple systems and Jordan triple systems. They were introduced by… …
