Finitistic extension degree
K Diveris - Algebras and Representation Theory, 2014 - Springer
We introduce the finitistic extension degree of a ring and investigate rings for which it is
finite. The Auslander–Reiten Conjecture is proved for rings of finite finitistic extension …

On a generalized Auslander-Reiten conjecture
It is well-known that the generalized Auslander-Reiten condition (GARC) and the symmetric
Auslander condition (SAC) are equivalent, and (GARC) implies that the Auslander-Reiten …

Auslander--Reiten conjecture for normal rings
K Kimura - arXiv preprint arXiv:2304.03956, 2023 - arxiv.org
In this paper, sufficient conditions for finitely generated modules over a commutative
noetherian ring to be projective are given in terms of vanishing of Ext modules. One of the …

Auslander–Reiten conjecture and finite injective dimension of Hom
D Ghosh, R Takahashi - Kyoto Journal of Mathematics, 2024 - projecteuclid.org
For a finitely generated module M over a commutative Noetherian ring R, we settle the
Auslander–Reiten conjecture when at least one of Hom R (M, R) and Hom R (M, M) has …

The Auslander-Reiten conjecture for Gorenstein rings
T Araya - Proceedings of the American Mathematical Society, 2009 - ams.org
The Nakayama conjecture is one of the most important conjectures in ring theory. The
Auslander-Reiten conjecture is closely related to it. The purpose of this paper is to show that …

The Auslander-Reiten conjecture for certain non-Gorenstein Cohen-Macaulay rings
S Kumashiro - Journal of Pure and Applied Algebra, 2023 - Elsevier
Abstract The Auslander-Reiten conjecture is a notorious open problem about the vanishing
of Ext modules. In a Cohen-Macaulay complete local ring R with a parameter ideal Q, the …

Algebras that satisfy Auslander's condition on vanishing of cohomology
LW Christensen, H Holm - Mathematische Zeitschrift, 2010 - Springer
Auslander conjectured that every Artin algebra satisfies a certain condition on vanishing of
cohomology of finitely generated modules. The failure of this conjecture—by a 2003 …

[HTML][HTML] An Auslander–Reiten principle in derived categories
M Ono, Y Yoshino - Journal of Pure and Applied Algebra, 2017 - Elsevier
We give a principle in derived categories, which lies behind the classical Auslander–Reiten
duality and its generalized version by Iyama and Wemyss. We apply the principle to show …

Gorenstein dimensions in trivial ring extensions
N Mahdou, K Ouarghi - Commutative Algebra and its Applications, 2009 - degruyter.com
In this paper, we show that the Gorenstein global dimension of trivial ring extensions is often
infinite. Also we study the transfer of Gorenstein properties between a ring and its trivial ring …
