摘要
本文研究范畴中态射的Drazin逆.给出了一般范畴中态射的{1m,2,5}逆的一个等价刻划.在Abel范畴中,建立指数与Drazin逆的概念,证明了有Drazin逆的态射必有柱心-幂零分解.
In this paper we establish the concepts of index and Drazin inverse for morphisms in an abelian category, prove that the morphisms for which the Drazin inverse edests must have core-nilpotent decomposition and give an equivalence characterization of the Drazin inverse.
