摘要
态射的Moore-Penrose逆是矩阵的Moore-Penrose逆在有对合*的范畴中的推广.本文着重给出具有满单泛分解态射f的{1,3,4}-逆和Moore-Penrose存在的充要条件,同时也推广了具有泛分解广义逆的相应结果.
In this paper, we define epic- monic universal- factorization of morphisms, and give existential conditions and expressions for the (1,3.4 )- inverses, Moore - Penrose iverses, in the mean - time, we generalize the corresponding results of morhisms with universal factorization.
