[PDF][PDF] Modules that have a supplement in every coatomic extension

B NişancıTürkmen - Miskolc Mathematical Notes, 2015 - real.mtak.hu
Let R be a ring and M be an R-module. M is said to be an E-module (respectively, an EE-
module) if M has a supplement (respectively, ample supplements) in every coatomic …

Projectivity relative to closed (neat) submodules

Y Durğun - Journal of Algebra and Its Applications, 2022 - World Scientific
An R-module F is called closed (neat) projective if, for every closed (neat) submodule L of
every R-module M, every homomorphism from F to M/L lifts to M. In this paper, we study …

Y Durgun, S Ozdemir - Journal of the Korean Mathematical Society, 2017 - koreascience.kr
A submodule N of a module M is called ${\mathcal {S}} $-closed (in M) if M/N is nonsingular.
It is well-known that the class Closed of short exact sequences determined by closed …

Pure-direct-injective modules

SK Maurya, S Das, Y Alagöz - Lobachevskii Journal of Mathematics, 2022 - Springer
In this paper, we study the class of modules having the property that if any pure submodule

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 …

When every S-flat module is (flat) projective
