正则环与YJ-内射性

Von Neumann Regular Rings and YJ-Injectivity

文献 [1]中 ,Ming.R.Y.C引进了 YJ 内射模的概念 ,且指出正则环上的每个模均是 YJ 内射模 ,那么反之如何呢 ?文 [1]中做了一些结果 ,本文拟就这个问题作进一步讨论 .

In the paper 1, Ming R.Y.C. introduced the concept of YJinjective module, and indicated that every module over a regular ring is YJinjective module. Then, whether is the converse true? Some results are obtained in 1. Further discussions about this problem will be developed in this paper.
