Y Liu - arXiv preprint arXiv:2211.16939, 2022 - arxiv.org
A triangulated category $\mathcal {C} $ with a canonical Bott's isomorphism $[2]\xrightarrow
{\sim} id $ is called a cyclic category in this paper. We give a new notion of stability …

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+ …

Stratifying systems and Jordan-H\"{o} lder extriangulated categories
Stratifying systems, which have been defined for module, triangulated and exact categories
previously, were developed to produce examples of standardly stratified algebras. A …

Y Qiu, X Zhang - arXiv preprint arXiv:2310.02917, 2023 - arxiv.org
Let $\mathcal {G} $ be a fusion category acting on a triangulated category $\mathcal {D} $, in
the sense that $\mathcal {D} $ is a $\mathcal {G} $-module category. Our motivation example …

[HTML][HTML] Triangulated subcategories of extensions, stable t-structures, and triangles of recollements
P Jørgensen, K Kato - Journal of Pure and Applied Algebra, 2015 - Elsevier
In a triangulated category T with a pair of triangulated subcategories X and Y, one may
consider the subcategory of extensions X⁎ Y. We give conditions for X⁎ Y to be triangulated …

On the existence of Auslander-Reiten -exangles in -exangulated categories
J He, J Hu, D Zhang, P Zhou - arXiv preprint arXiv:2110.02476, 2021 - arxiv.org
Let $\mathscr {C} $ be an $ n $-exangulated category. In this note, we show that if $\mathscr
{C} $ is locally finite, then $\mathscr {C} $ has Auslander-Reiten $ n $-exangles. This unifies …
