Auslander–Reiten conjecture of the tilting theorem

AM Fallah - Journal of Algebra and Its Applications, 2024 - World Scientific
Let Λ be a Noetherian algebra and T∈ Λ-mod be an n-tilting module with Γ= End Λ (T). Then
Λ satisfies Auslander–Reiten conjecture if and only if so does Γ. As a consequence, we …

Auslander-Reiten conjecture in a dual vein

H Eshraghi, A Mahin Fallah - Algebras and Representation Theory, 2021 - Springer
We consider a dual notion of the famous Auslander-Reiten Conjecture in case of Noetherian
algebras over commutative Noetherian rings. Firstly, in the introduction, we will examine its …

Generalization of Auslander-Reiten duality for algebras

A Mahin Fallah - Communications in Algebra, 2021 - Taylor & Francis
Let R be a Cohen-Macaulay local ring of dimension d with canonical module ωR. In this
article we extend Auslander-Reiten duality theorem to certain R-algebras. As a …

On the Auslander–Reiten conjecture for Cohen–Macaulay rings and path algebras

A Bahlekeh, T Kakaei, S Salarian - Communications in Algebra, 2017 - Taylor & Francis
In this note, it is shown that the validity of the Auslander–Reiten conjecture for a given d-
dimensional Cohen–Macaulay local ring R depends on its validity for all direct summands of …

The Auslander-Reiten Conjecture for Group Rings

A Bahlekeh - Iranian Journal of Mathematical Sciences and …, 2022 - ijmsi.ir
This paper studies the vanishing of $ Ext $ modules over group rings. Let $ R $ be a
commutative noetherian ring and $ ga $ a group. We provide a criterion under which the …

Excellent extensions and homological conjectures

Y Zhang - Algebra Colloquium, 2018 - World Scientific
In this paper, we introduce the notion of excellent extensions of rings. Let Γ be an excellent
extension of an Artin algebra Λ, we prove that Λ satisfies the Gorenstein symmetry …
