A module satisfying the descending chain condition on cyclic submodules is called
coperfect. The class of coperfect modules lies properly between the class of locally artinian …

In this paper, we give new categorical characterizations of (dual-) Baer modules and then
several applications of them are presented. Among other things, it is proved that a module …

The identification problem of an inclusion is considered in the paper. The inclusion is
unknown subdomain of a given physical region. The available information on the inclusion …

Since 2004, Baer modules have been considered by many authors as a generalization of
the Baer rings. A module MR is called Baer if every intersection of the kernels of …

Let $ M_R $ be a non-zero‎‎ module and ${\mathcal F}‎:‎\sigma [M_R]\times\sigma
[M_R]‎‎\rightarrow $ Mod-$\Bbb {Z} $ a bifunctor‎.‎ The‎‎ $\mathcal {F} $-reversibility of $ M $ is …

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 $0\rightarrow X\rightarrow M\rightarrow Y\rightarrow 0$ with …

In this paper, we will discuss and study the structure of quasi-coretractable modules. Some
characterization theorems of quasi-coretractable modules in terms of Kasch rings, CS …
