Quotient categories with exact structure from -rigid subcategories in extriangulated categories
In this work we introduce the notion of higher $\mathbb {E} $-extension groups for an
extriangulated category $\mathcal {C} $ and study the quotients $\mathcal {X} _ {n+ …

Cut notions in extriangulated categories related to Auslander-Buchweitz theory and cotorsion theory
In this work we introduce notions in Auslander-Buchweitz theory and cotorsion theory in
extriangulated categories which extend the given ones for abelian categories. Although …

Rigid subcategories and related subcategories in extriangulated categories
Z Zhang, S Wang - Communications in Algebra, 2023 - Taylor & Francis
In this paper, we firstly obtain the analogue of a Bongartz completion for functorially finite
rigid subcategories in an extriangulated category and then we investigate the properties of n …

Mutation of -cotorsion pairs in triangulated categories
H Chang, P Zhou - arXiv preprint arXiv:2404.18336, 2024 - arxiv.org
In this article, we define the notion of $ n $-cotorsion pairs in triangulated categories, which
is a generalization of the classical cotorsion pairs. We prove that any mutation of an $ n …
