Tensor and torsion products of relative injective modules with respect to a semidualizing module

M Salimi, E Tavasoli, S Yassemi - Communications in Algebra, 2015 - Taylor & Francis
Let R be a commutative Cohen–Macaulay ring, and let C be a semidualizing module of R. In
this paper, we show that C is generically dualizing if and only if the tensor products of …

Tensor Product of -Injective Modules

M Rahmani, AJ Taherizadeh - arXiv preprint arXiv:1503.05492, 2015 - arxiv.org
Let $ R $ be a Noetherian ring and let $ C $ be a semidualizing $ R $-module. In this paper,
we are concerned with the tensor and torsion product of $ C $-injective modules. Firstly, it is …

Presentations of rings with non-trivial semidualizing modules

DA Jorgensen, GJ Leuschke… - Collectanea mathematica, 2012 - Springer
Let R be a commutative noetherian local ring. A finitely generated R-module C is
semidualizing if it is self-orthogonal and\rm Hom _R (C, C) ≅ R. We prove that a Cohen …

A criterion for dualizing modules

K Divaani-Aazar, MN Babaei… - Tokyo Journal of …, 2015 - projecteuclid.org
We establish a characterization of dualizing modules among semidualizing modules. Let $
R $ be a finite dimensional commutative Noetherian ring with identity and $ C $ a …

Multiplicities of semidualizing modules

SM Cooper, S Sather-Wagstaff - Communications in Algebra, 2013 - Taylor & Francis
A finitely generated module C over a commutative noetherian ring R is semidualizing if Hom
R (C, C)≅ R and for all i≥ 1. For certain local Cohen–Macaulay rings (R, 𝔪), we verify the …

Tensor and torsion products of injective modules

EE Enochs, OMG Jenda - Journal of Pure and Applied Algebra, 1991 - Elsevier
Yoneda raised the question of whether the tensor product of injective modules is injective.
Ishikawa showed that for a commutative noetherian ring R this is the case if the injective …

Syzygy and torsionless modules with respect to a semidualizing module

M Salimi, E Tavasoli, P Moradifar… - … and Representation Theory, 2014 - Springer
This paper aims at generalizing the notions of “Auslander dual”,“k-torsionless” and “k-th
syzygy” modules to the relative setting with respect to a semidualizing module. It is shown …

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 …

Semidualizing modules over numerical semigroup rings

E Celikbas, H Geller, T Kobayashi - arXiv preprint arXiv:2306.14989, 2023 - arxiv.org
A semidualizing module is a generalization of Grothendieck's dualizing module. For a local
Cohen-Macaulay ring $ R $, the ring itself and its canonical module are always realized as …
