On Moore----Penrose Inverses Of Matrices a Ring

ABSTRACT

This paper mainly discussed the Moore----Penrose inverses of matrฎices about general ring matrix and the ring R with an involution * and unitary. And we discussed some sufficient conditions for the e⌚xis▲tence of Moore----Penrose inverses of matri☂ces over a ring R are given.

Keyword♛s: ring, matrix; *--symmetric; Moore----Penrose inverse.
