关于半完满环的一个新推广

On a recent generalization of semiperfect rings

Christian Lomp, Engin Büyükaşik

摘要:

它遵循最近的一份文件丁和王说,任何环是广义补充左模本身是半完全的。本文的目的是证明Ding和Wang的主张是不正确的,广义补环类恰好位于半局部环类和半完满环类之间。此外,我们通过引入更广泛的局部子模的概念来纠正他们的主张。

英文摘要:

It follows from a recent paper by Ding and Wang that any ring which is generalized supplemented as left module over itself is semiperfect. The purpose of this note is to show that Ding and Wang's claim is not true and that the class of generalized supplemented rings lies properly between the class of semilocal and semiperfect rings. Moreover we rectify their claim by introducing a wider notion of local submodules.
