Pure-direct-injective modules
In this paper, we study the class of modules having the property that if any pure submodule
is isomorphic to a direct summand of such a module then the pure submodule is itself a …

On simple-direct modules
E Büyükaşık, Ö Demir, M Diril - Communications in Algebra, 2021 - Taylor & Francis
Recently, in a series of papers “simple” versions of direct-injective and direct-projective
modules have been investigated. These modules are termed as “simple-direct-injective” and …

[HTML][HTML] Simple-direct-injective modules
A module M over a ring is called simple-direct-injective if, whenever A and B are simple
submodules of M with A≅ B and B⊆⊕ M, we have A⊆⊕ M. Various basic properties of …

Simple-direct-projective modules
In this paper, we introduce and study the dual notion of simple-direct-injective modules.
Namely, a right R-module M is called simple-direct-projective if, whenever A and B are …

Semisimple-direct-injective modules
The notion of simple-direct-injective modules which are a generalization of injective
modules unifies $ C2 $ and $ C3 $-modules. In the present paper, we introduce the notion of …

On modules and rings in which complements are isomorphic to direct summands
Abstract A right R-module M is virtually extending (or CIS) if every complement submodule of
M is isomorphic to a direct summand of M, and M is called a virtually C2-module if every …

Self mini-injective rings
M Harada - 1982 - projecteuclid.org
Let R be a ring. We have studied rings whose projective modules have the extending
property of simple modules in [3] and [5]. In this note, we shall further study those rings when …

Some decomposition properties of injective and pure-injective modules
JL Garcia, NV Dung - 1994 - projecteuclid.org
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] …
