Filtered-injective and coflat modules

D Döman, GJ Hauptfleisch - Quaestiones Mathematicae, 1978 - Taylor & Francis
For an arbitrary left R-module M, we denote by F (M) the class of left R-modules F such that
for any exact sequence 0→ A α→ B of left R-modules and any R-homomorphism β: A→ M …

On some Artinian QF-3 rings

DV Huynh - Communications in Algebra, 2014 - Taylor & Francis
Carl Faith in 2003 introduced and investigated an interesting class of rings over which every
cyclic right module has Σ-injective injective hull (abbr., right CSI-rings). Inspired by this we …

[PDF][PDF] Strongly prime ideals in CS-rings

G GÜNGÖROĞLU - Turkish Journal of Mathematics, 2000 - journals.tubitak.gov.tr
Throughout this paper all rings will be associative with identity and modules will be unital
right modules. A ring R is called right CS-ring (or extending ring) if every right ideal I in R is …

Rings whose CS modules are countably Σ-CS

N Er - Communications in Algebra, 2003 - Taylor & Francis
A module M is called a CS module if every submodule of M is essential in a direct summand
of M. In this paper, among other results, we prove that for a ring R with finitely generated …

[引用][C] A note on perfect rings

B Nashier, W Nichols - manuscripta mathematica, 1991 - Springer
In the seminal paper [1], Bass provided a number of characterizations of left perfect rings. In
the course of the proof of his" Theorem P", Bass implicitly showed that the ring R is left …

A counterexample for CS-rings

GF Birkenmeier, JY Kim, JK Park - Glasgow Mathematical Journal, 2000 - cambridge.org
A module M is called a CS-module or an extending module if every submodule is essential
