Restricted-finite groups with some applications in group rings

B. Taeri, M. R. Vedadi

We carry out a study of groups $G$ in which the index of any infinite subgroup is finite. We call them restricted-finite groups and characterize finitely generated not torsion rest…

A new approach to Baer and dual Baer modules

N. Ghaedan, M. R. Vedadi

Let $R$ be a ring. It is proved that an $R$ -module $M$ is Baer (resp. dual Baer) if and only if every exact sequence $0 \to X \to M \to Y \to 0$ with $Y…

Two Generalizations of the Wedderburn-Artin Theorem with Applications

Mahmood Behboodi, Asghar Daneshvar, Mohammad Reza Vedadi

We say that an $R$ -module $M$ is {\it virtually simple} if $M \neq = (0)$ and $N ≅ M$ for every non-zero submodule $N$ of $M$ , and {\it virtually semisimple} if each submodule of $…

Virtually Semisimple Modules and a Generalization of the Wedderburn-Artin Theorem

Mahmood Behboodi, Asghar Daneshvar, Mohammad Reza Vedadi

By any measure, semisimple modules form one of the most important classes of modules and play a distinguished role in the module theory and its applications. One of the most fundam…
