摘要
本文讨论预加法范畴中态射的广义Moore-Perurose逆．给出了具有泛分解态射的广义Moore-Penrose逆存在的几个充要条件,并把结果应用到环上的矩阵中．
The generalized Moore-Penrose inverses of morphisms over a preadditive category with an involution ＊ are studied. Some necessary and sufficient conditions for existence of the generalized Moore-Penrose inverses of morphisms with universal factorization are given. And, some applications are given to matrices concerning factorizations over some rings.
