[PDF][PDF] On Purely–Extending Modules
B Al-Bahrani - Iraqi Journal of Science, 2013 - iasj.net
In this note we consider a generalization of the notion of a purely extending modules,
defined using y–closed submodules. We show that a ring R is purely y–extending if and only …

CS-Rickart modules
In this paper, we introduce and study the concept of CS-Rickart modules, that is a module
analogue of the concept of ACS rings. A ring R is called a right weakly semihereditary ring if …

The rings characterized by minimal left ideals
JC Wei - Acta Mathematica Sinica, 2005 - Springer
We study these rings with every minimal left ideal being a projective, direct summand and ap–
injective module, respectively. Some characterizations of these rings are given, and the …

Weak injective and weak flat modules
Z Gao, F Wang - Communications in Algebra, 2015 - Taylor & Francis
Let R be a ring. A left R-module M (resp., right R-module N) is called weak injective (resp.,
weak flat) if (resp.,) for every super finitely presented left R-module F. By replacing finitely …

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 …
