The Rings Characterized by Minimal Left Ideals
AbstractWe study these rings with every minimal left ideal being a projective, direct summand and a p–injective module, respectively. Some characterizations of these rings are given, and the
A NOTE ON DIRECT-INJECTIVE MODULES
In this paper, we study some more properties on direct-injective modules in the context of endoregular, SSP and SIP modules. We find the equivalent condition for a directinjective module to be
DIRECT PROJECTIVE MODULES WITH THE SUMMAND SUM PROPERTY
Let R be a ring with a unity and let M be a unitary left R-module. In this paper, we establish [5, Proposition 2.8] by showing the proof of it. Moreover, from the above result, we obtain some
Some Generalizations of Quasi-Projective Modules
In this paper, the concepts of SGQ-projective, quasi-epi -projective and quasi-epi -projective modules are introduced and some properties of these modules are investigated. Hopfian and co-Hopfian
EQUIVALENT CONDITIONS FOR A DIRECT INJECTIVE MODULE
The purpose of this paper is to find the necessary find sufficient conditions for a module to be a direct injective module. Moreover, we focus on the possibility that a direct injective module can be
Rings whose cyclics are C3-modules
This is a study of rings whose cyclic modules are D3-modules with applications to rings whose cyclics are quasi-discrete and, respectively, discrete.
A Study On Semi-projective Covers, Semi-projective Modules and Formal Triangular Matrix Rings
We show that a ring R is right perfect if and only if every right R-module has a semi-projective cover. We characterize (semi)hereditary and semisimple rings via semi- projective modules. Finally we
Relatively Semiregular Modules
The notion of δ-semiregular modules is introduced in terms of δ-small submodules. It is shown that a ring R is a δ-semiregular ring if and only if RR is a δ-semiregular module, if and only if RR is a
On Slightly Compressible-Injective Modules
In this paper, we introduce the concept of slightly compressible-injective modules, following this, a right R-module N is called an M-slightly compressible-injective module, if every R-homomorphism
D3-Modules
A right R-module M is called a D3-module, if M 1 and M 2 are direct summands of M with M = M 1 + M 2, then M 1 ∩ M 2 is a direct summand of M. Following the work of Bass on projective covers, we

Characterization of rings using quasiprojective modules
Semisimple, semiperfect, and perfect rings are characterized by quasiprojective modules and quasiprojective covers over them.

K. Morita has shown that, given two rings R and S, there is an isomorphism between the category of left R-modules and the category of left S-modules if and only if there exists an R-S bimodule U such
QUASI-PROJECTIVE COVERS AND DIRECT SUMS
In this paper R denotes an associative ring with an identity, and all modules are unital left R-modules. It is shown that the existence of a quasi-projective cover for each module implies that each
Semiregular Modules and Rings
Mares [9] has called a projective module semiperfect if every homomorphic image has a projective cover and has shown that many of the properties of semiperfect rings can be extended to these modules.
Quasi-Injective and Pseudo-Infective Modules
Let R be a ring with identity not equal to zero. A right R-module is said to be quasi-injective (pseudo-injective) if for every submodule N of M, every R-homomorphism (R-monomorphism) of N into M can
Rings and Categories of Modules
This book is intended to provide a self-contained account of much of the theory of rings and modules. The theme of the text throughout is the relationship between the one-sided ideal structure a ring

An Introduction to Homological Algebra discusses the origins of algebraic topology. It also presents the study of homological algebra as a two-stage affair. First, one must learn the language of Ext
