单模的扩张与Schur引理的逆
Extensions of Simple Modules and the Converse of Schur's Lemma
摘要:
模范畴上Schur引理(或CSL)条件的逆是近年来研究的一个重要课题。在本说明中,我们扩展了工作,开发的基本性质的模块类别中的CSL条件管理模块的有限长度。
英文摘要:
The converse of Schur's lemma (or CSL) condition on a module category has been the subject of considerable study in recent years. In this note we extend that work by developing basic properties of module categories in which the CSL condition governs modules of finite length.
