摘要
本文以态射偶的等化子为工具研究态射的广义逆 ,对于态射 f,给出了 g为 f-,f D和 f+的充要条件 。
The generalized inverse of morphisms is studied through equalizer,the necessary and sufficient conditions of which a morphism g is f -,f D,and f + respectly are given, the relation between the linear equation and equalizer is presented in matrix category.
