本文研究任意Krull—Schmidt范畴中的右极小态射.利用半完全环众所周知的理论,证明了任意Krull.Schmidt范畴中右极小态射的基本定理,推广了具有有限长度模范畴上的经典结果
In this article, we study the right minimal morphisms in arbitrary Krull-Schmidt categories. Using well-known results on semiperfect rings, we prove the fundamental theorem of right minimal morphisms in arbitrary Krull-Schmidt categories. This generalizes the classical result [1, p.6] on the category of modules of finite length.
