m-weak group inverses in a ring with involution

Rings and Algebras 2020-08-03 v1

Abstract

In a unitary ring with involution, we prove that each element has at most one weak group inverse if and only if each idempotent element has a unique weak group inverse. Furthermore, we define the mm-weak group inverse and show some properties of mm-weak group inverse.
