Rings and Algebras 2016-01-29 v1

Abstract

Let RR be a unital ring with involution.In this paper, several new necessary and sufficient conditions for the existence of the Moore-Penrose inverse of an element in a ring RR are given.In addition, the formulae of the Moore-Penrose inverse of an element in a ring are presented.
