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 …

On Simple Singular YJ-injective Modules.
J Wei - Southeast Asian Bulletin of Mathematics, 2007 - search.ebscohost.com
We investigate the strongly regularity of rings whose simple singular right R-modules are YJ-
injective. It is proved that the following conditions are equivalent for a ring R:(1) R is a …

The opposite of injectivity by proper classes
Proper classes (or exact structures) offer rich research topics due to their important role in
category theory. Motivated by the studies on opposite of injective modules, we introduce a …

Rings with indecomposable right modules local
S Singh - Taiwanese Journal of Mathematics, 2010 - projecteuclid.org
Every indecomposable module over a generalized uniserial ring is uniserial, hence local.
This motivates one to study rings R satisfying the condition (*): R is a right artinian ring such …

[PDF][PDF] Minimal quasi-injective modules
Z Zhu, Z Tan - Scientiae Mathematicae Japonicae, 2005 - jams.or.jp
Let R be a ring. A right R-module M is called minimal quasi-injective if every homomorphism
from a simple submodule of M to M can be extended to an endomorphism of M. Some …

Regular self-injective rings andV-rings
DV Tyukavkin - Algebra and Logic, 1994 - Springer
Regular, right self-injective rings are considered. We settle the question of when such a ring
is a right V-ring, ie, when each simple right module over the ring is injective. It is proved that …
