Cofinitely Essential G-Supplemented Modules

Abstract

LetM be an R-module. If every cofinite essential submodule ofM has a g-supplement in M, then M is called a cofinitely essential g-supplemented (or briefly cofinitely eg-supplemented) module. In this work, some properties of these modules are investigated. It is proved that every factor module and every homomorphic image of a cofinitely eg-supplemented module are cofinitely eg-supplemented. Let M be a cofinitely eg-supplemented module. Then every M-generated R-module is cofinitely eg-supplemented.
