Xiaoxiang Zhang, Shuangshuang Zhang, Jianlong Chen, Long Wang

摘要:

本文研究了具有对合环$R$上投影的差与积的MP逆。得到了一些等价条件。作为应用,刻画了交换子$pq-qp$和反交换子$pq+qp$的MP可逆性,其中$p$和$q$是在$R$中的投影.推广了$C^*$ -代数中的一些相关结果.

英文摘要:

This article concerns the MP inverse of the differences and the products of projections in a ring $R$ with involution. Some equivalent conditions are obtained. As applications, the MP invertibility of the commutator $pq-qp$ and the anti-commutator $pq+qp$ are characterized, where $p$ and $q$ are projections in $R$. Some related known results in $C^*$-algebra are generalized.
