Existence criteria and expressions of the (b,c)-inverse in rings and its applications. (arXiv:1706.07775v1 [math.RA])
来源于:arXiv
Existence criteria for the $(b,c)$-inverse are given.% in terms of
annihilators. We present explicit expressions for the $(b,c)$-inverse by using
inner inverses. We answer the question when the $(b,c)$-inverse of $a\in R$ is
an inner inverse of $a$. As applications, we give a unified theory of some
well-known results of the $\{1,3\}$-inverse, the $\{1,4\}$-inverse, the
Moore-Penrose inverse, the group inverse and the core inverse. 查看全文>>
