摘要
本文引入了环的不变σ—理想和模的σ—派生模等概念,并建立了它们的若干基本性质.同时,还指出并修正了文〔2—4〕中的几个不妥之处.
In this paper we hav introduced the notions of the σ-inva- riant ideals of a ring and the σ-deri- vative module of a module,establi- shedtheir some fundamental proper- ties,Moreover,we have pointed out and corrected some mistakes in re- ferences[2-4]
