C^*代数上pseudo DMP逆的研究

在条件a=abb^(1,3)、bc=ca,b^*c=ca*及ab=ba下研究pseudo DMP逆及dual pseudo DMP逆在C^*代数上特征及反序。同时,根据m-EP元素的定义与性质,探讨C^*代数上pseudo DMP逆、dual pseudo DMP逆和Moore-Penrose逆的关系。

Asymptotic Direct System of C^(*)-algebras and Locally AF-algebra

We define the direct limit of the asymptotic direct system of C^(*)-algebras and give some properties of it.Finally,we prove that a C^(*)-algebra is a locally AF-algebra,if and only if it is the direct limit of an asymptotic direct system of finite-dimensional C^(*)-algebras.
