Necessary and sufficient conditions on a ring R are found under which all surjective
endomorphisms of finitely generated right R-modules are automorphisms. Namely, this …

A module M has the property (V) il for every K< M, KIM and me MK, any submodule-L
maximal, with respect to the property that it contains K but does not contain the element m, is …

In this sequel to [21] and [33], further properties of rings whose simple left modules axe
either YJ-injective or projective are developed. Division rings are characterized. Fully left …

A ring R is called a left (right) SF-ring if simple left (right) R-modules are flat. It is still
unknown whether a left (right) SF-ring is von Neumann regular. In this paper, we give some …

A ring R is a right SI-ring if every singular right R-module is injective, while R is a right S3I-
ring if every singular semisimple right R-module is injective. In this paper, we investigate and …

This paper is concerned with rings for which all modules in one of the following classes are
injective: simple modules, quasi-injective modules, or proper cyclic modules. Such rings are …

A ring R is called left weakly np-injective if for each non-nilpotent element a of R, there exists
a positive integer n such that any left R-homomorphism from $ Ra^ n $ to R is right …

Let S be an m-system of a ring R, and P a submodule of a right R-module M. This paper,
presents the notion of S-prime submodule and provides some properties and equivalent …
