Cofinitely Semisimple (ss-) Lifting Modules

Abstract

An $R-$module $N$ is named cofinitely semisimple lifting or briefly cofinitely $ss-$lifting if for each cofinite submodule $S$ of $N$, $N$ has a decomposition $N=U'\oplus V$ such that $U'\subseteq S$ and $S\cap V\subseteq Soc_{s}(V)$. In this study, equivalent conditions to this definition are given. In addition, the basic features of this concept defined in this article are examined.
