From subcategories to the entire module categories

R Hafezi - Forum Mathematicum, 2021 - degruyter.com
In this paper we show that how the representation theory of subcategories (of the category of
modules over an Artin algebra) can be connected to the representation theory of all modules …

On 1-Gorenstein Algebras of Finite Cohen–Macaulay Type

R Hafezi, J Asadollahi, Z Karimi - Michigan Mathematical Journal, 2023 - projecteuclid.org
An Artin algebra Λ is said to be of finite Cohen–Macaulay type if, up to isomorphism, there
are only finitely many indecomposable modules in G (Λ), the full subcategory of modΛ …

R Hafezi - arXiv preprint arXiv:2109.00467, 2021 - arxiv.org
Let $\text {Gprj}\mbox {-}\Lambda $ denote the category of Gorenstein projective modules

Auslander-Reiten duality for subcategories

R Hafezi - arXiv preprint arXiv:1705.06684, 2017 - arxiv.org
Auslander-Reiten duality for module categories is generalized to some sufficiently nice
subcategories. In particular, our consideration works for $\mathcal {P}^{<\infty}(\Lambda) …

[PDF][PDF] On cohen-macaulay auslander algebras

R Hafezi - arXiv preprint arXiv:1802.05156, 2018 - researchgate.net
Cohen-Macaulay Auslander algebras are the endomorphism algebras of representation
generators of the subcategory of Gorenstein projective modules over CM-finite algebras. In …

On the existence of recollements of functor categories

R Vahed - Communications in Algebra, 2020 - Taylor & Francis
A sufficient condition for the existence of recollements of functor categories is provided.
Using this criterion, we show that a recollement of rings induces a recollement of their path …
