具有广义分解的态射的广义Moore-Penrose逆

摘要

研究了预加范畴中具有广义分解的态射的广义Moore—Penrose逆，并给出了广义Moore—Penrose逆存在的充要条件及其表达式．%This paper studies the general Moore-Penrose inverse of morphism with general factorization in a preadditive category, and gives some necessary and sufficient conditions for the existence and expressions of general Moore-Penrose inverse.
