关于基本内射模的注记

A note on essentially injective modules

基本内射性是ojectivity的推广.首先讨论了基本内射模和基本ojective模的一致性,并证明了两者是一致的;给出了基本内射模的定义,并用类似于内射模的研究方法得到了基本内射模的Baer准则等性质.

Essentially injectivity is a generalization of ojectivity. The concept of essentially injective module was presented. It was proved that essentially injective modules and essentially ojective modules were consistent. Similarly to the injective module, some properties of essentially injective modules, such as Baer Criterion were established.
