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 …

Abelian quotients of categories of short exact sequences

Z Lin - Journal of Algebra, 2020 - Elsevier
We mainly investigate abelian quotients of categories of short exact sequences. The natural
framework to consider the question is via identifying quotients of morphism categories as …

Different exact structures on the monomorphism categories

R Hafezi, I Muchtadi-Alamsyah - Applied Categorical Structures, 2021 - Springer
Let XX be a contravariantly finite resolving subcategory of mod-\varLambda mod-Λ, the
category of finitely generated right\varLambda Λ-modules. We associate to XX the …

Brauer-Thrall type theorems for submodule categories

J Asadollahi, R Hafezi, Z Karimi - Communications in Algebra, 2021 - Taylor & Francis
Let Λ be an artin algebra and X be a quasi-resolving subcategory of mod-Λ which is of finite
type. Let SX (Λ) be the full subcategory of the morphism category H (Λ) consisting of all …
