An R-module hf is called extending (or a CS-module) if every submodule of M is essential in
a direct summand of M. The module M is called C-eztendzng (resp., finitely or countably C …

It is well known that a countably injective module is Σ-injective. In [KI Beidar, SK Jain, Ashish

It is well known that over a left Notherian ring any direct sum of injecive modules is again
injective, and every injective module is a direct sum of indecomposable modules. Faith [6] …

Pure-injective and RD-injective R-modules over domains R have been investigated by many
authors. We introduce another class of R-modules, called weak-injective modules, which …

Rosenberg and Zelinsky [6] first addressed the question of characterizing for a ring R those
simple modules RT having injective hulls of finite length. In that work they also announced a …

A pure-injective module M is said to be pi-indigent if its subinjectivity domain is smallest
possible, namely, consisting of exactly the absolutely pure modules. A module M is called …
