关于广义逆的注记

Remarks About Generalized Reverse

本文得到下列结果:命题1,在算子代数A 中充分必要条件(1,2)—A 存在的广义逆是(1)—A 存在的广义逆。命题2,让F 是一个域,4∈F^(mrn),(1.2)—A 的广义逆总是存在的.

This paper obtained the following results:Theorem 1.In Operator Algebra (?),the uecessary and sufficient condition.that(1,2)- Generalized Re-versc of A exists is that(1)-Generalized Reverse of Aexists.Theorem 2.Let F be a field,A (?)F^(?),(1,2)-Generalized Reverse of A always exists.
