摘要
本文主要研究PS-内射环,作为morphic-环的推广,我们引入了一类PS-内射环,称之为J-morphic环.给出了J-morphic环的例子和一些性质.最后还研究了在平凡扩张下的内射性.
The aim of this paper is to investigate the principally small injective rings. As a generalization of the morphic rings, we introduce a class of principally small injective rings which is called J-morphic rings. Some properties and examples are given. Finally, we also study the principally small injectivity under trivial ring extensions.
