摘要:

给出了Wnil-内射模的一些性质及刻画, 并在单奇异左模是Wnil-内射的条件下讨论了一些特殊环(如约化环、 半素环、 拟ZI-环等)之间的关系.

关键词: Wnil-内射模, NI-环, 左半中心, ZC-环, 拟ZI-环

Abstract:

We gave some properties and characterizations of Wnilinjective modules, and under the condition that every simple singular left module is Wnilinjective, we discussed the relationship of some special rings (such as reduced rings, semiprime rings and quasi ZI-rings).

Key words: Wnilinjective module, NI-rings, semicentral, ZC-rings, quasi ZI-rings
