Neat and coneat submodules of modules over commutative rings

S Crivei - Bulletin of the Australian Mathematical Society, 2014 - cambridge.org
We prove that neat and coneat submodules of a module coincide when is a commutative
ring such that every maximal ideal is principal, extending a recent result by Fuchs. We …

On cofinitely injective modules

VA Hiremath - Journal of the London Mathematical Society, 1978 - Wiley Online Library
In this paper, we introduce the notion of cofinitely injective modules and study their
properties over special types of rings. We define a right R‐module M to be cofinitely injective …

[PDF][PDF] The structure of extending modules over Noetherian rings

MA Kamal, BJ Müller - 1988 - projecteuclid.org
A module is said to be extending, if every closed (ie complement) submodule is a direct
summand. This property is usually denoted by (Q). It is, obviously, equivalent to the …

Flatness and injectivity of simple modules over a commutative ring

J Xu - Communications in Algebra, 1991 - Taylor & Francis
In this short paper, the homological functors are used to show that a simple module is flat if
and only if it is injective. It is used to give a characterization of Von Neumann regular ring …

Thick subcategories of modules over commutative Noetherian rings (with an appendix by Srikanth Iyengar)

H Krause - Mathematische Annalen, 2008 - Springer
For a commutative noetherian ring A, we compare the support of a complex of A-modules
with the support of its cohomology. This leads to a classification of all full subcategories of A …

Modules whose closed submodules with essential socle are direct summands

S Crivei, S Şahinkaya - 2014 - projecteuclid.org
We introduce and study CLESS-modules, which subsume two generalizations of extending
modules due to PF Smith and A. Tercan. A module M will be called a CLESS-module if every …

Catenary modules

S Namazi, H Sharif - Acta Mathematica Hungarica, 1999 - Springer
We generalise the concept of catenary rings to modules. We call an A-module M catenary if
for each pair of prime submodules K and L of M with K⊂ L all saturated chains of prime …

Tests for injectivity of modules over commutative rings

LW Christensen, SB Iyengar - Collectanea mathematica, 2017 - Springer
It is proved that a module M over a commutative noetherian ring R is injective if Ext _ R^ i
((R/\mathfrak p) _\mathfrak p, M)= 0 Ext R i ((R/p) p, M)= 0 holds for every i\geqslant 1 i⩾ 1 …
