Wnil-内射模的若干性质及刻画

摘要

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 Zl-rings ).%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.
