環(huán)上矩陣的廣義Moore----Penrose逆
中文摘要
本文主要討論1般環(huán)矩陣和帶有對合反自同構*有單位元的環(huán)上矩陣的廣義Moore---Penrose逆.并給出它們的廣義Moore---Penrose逆存在的幾個充要條件.
關鍵詞：環(huán)；矩陣；*對稱；廣義Moore----Penrose逆.
On Moore----Penrose Inverses Of Matrices a Ring
ABSTRACT
This paper mainly discussed the Moore----Penrose inverses of matrices about general ring matrix and the ring R with an involution * and unitary. And we discussed some sufficient conditions for the existence of Moore----Penrose inverses of matrices over a ring R are given.
Keywords: ring, matrix; *--symmetric; Moore----Penrose inverse.
