On Two Classes of Modules Related to CS Trivial Extensions

Rings and Algebras 2021-12-21 v1

Abstract

All rings considered are commutative. In this article we introduce and study two notions of modules which are stronger than CS modules, namely weakly IN modules and strongly CS modules. Our main aim is to characterize when a trivial extension A=RMA=R\propto M (of a ring RR by an RR-module MM) is a CS ring.
