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 …

Characterizations of some rings with C-projective, C-(FP)-injective and C-flat modules
XG Yan, XS Zhu - Czechoslovak mathematical journal, 2011 - Springer
Let R be a commutative ring and C a semidualizing R-module. We investigate the relations
between C-flat modules and C-FP-injective modules and use these modules and their …

A note on semi-projective modules
H Tansee, S Wongwai - Kyungpook Mathematical Journal, 2002 - koreascience.kr
Quasi-principally injective modules were studied in [12]. In this note we introduce the
concept dual to quasi-principally injective modules. It is proved that. these modules are …

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 …

C-Injective rings
L Shen, F Feng, W Li - Journal of Algebra and Its Applications, 2022 - World Scientific
A ring R is called a right C-injective ring if every homomorphism from a closed right ideal of
R to RR can be extended to one from RR to RR. It is clear that a right CS ring must be right C …

[PDF][PDF] Small principally quasi-injective modules
S Wongwai - Int. J. Contemp. Math. Sciences, 2011 - m-hikari.com
Let M be a right R-module. A right R-module N is called small principally M-injective (briefly,
SP-M-injective) if, every R-homomorphism from a small and principal submodule of M to N …

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 …
