Abstract:
In this paper, we introduce the concept of modules with the properties (RE) and (SRE), and we provide various properties of these modules. In particular, we prove that a semisimple module $M$ is $\operatorname{Rad}$-supplementing if and only if $M$ has the property (SRE). Moreover, we show that a ring $R$ is a left V-ring if and only if every left $R$-module with the property (RE) is injective. Finally, we characterize the rings whose modules have the properties (RE) and (SRE).
Keywords:$\operatorname{Rad}$-supplement, module with the properties (RE) and (SRE), artinian serial ring.
