In this paper, we study the behavior of endomorphism rings of indecomposable (uniform) quasi-injective modules. A very natural question here is, for a morphism , with indecomposable (uniform) quasi-injective right -modules, and an extension of where denotes the injective hull, what is the relation between kernels of and , their monogeny classes and their upper parts?

均匀准内射模之间的同态核
在本文中,我们研究了不可分解(一致)准内射模的自同态环的行为。这里一个非常自然的问题是,对于态射, 和不可分解的(一致的)准内射权-模块,和的延伸在哪里表示单射外壳,内核之间的关系是什么和,他们的单生阶级和他们的上半部分?
