From n-exangulated categories to n-abelian categories

Y Liu, P Zhou - Journal of Algebra, 2021 - Elsevier
Abstract Herschend-Liu-Nakaoka introduced the notion of n-exangulated categories. It is not
only a higher dimensional analogue of extriangulated categories defined by Nakaoka-Palu …

Hereditary -exangulated categories

J He, J He, P Zhou - arXiv preprint arXiv:2401.00777, 2024 - arxiv.org
Herschend-Liu-Nakaoka introduced the concept of $ n $-exangulated categories as higher-
dimensional analogues of extriangulated categories defined by Nakaoka-Palu. The class of …

Ideal approximation in -exangulated categories

Y Wang, J Wei - arXiv e-prints, 2022 - ui.adsabs.harvard.edu
In this paper, we study the ideal approximation theory associated to almost $ n $-exact
structures in the $ n $-exangulated category. The notions of $ n $-ideal cotorsion pairs and …

Z Xie, Z Liu, X Yang - Applied Categorical Structures, 2022 - Springer
Let T be ak-linear Hom-finite (n+ 2)-angulated category with n-suspension functor Σ n, split
idempotents, and Serre functor S. Let T be an Oppermann–Thomas cluster tilting object in T …

Z Xie, Z Liu, Z Di - Journal of Algebra and Its Applications, 2021 - World Scientific
Let k be an algebraically closed field, n≥ 1 an integer, 𝒯 ak-linear Hom-finite (n+ 2)-
angulated category with n-suspension functor Σ n, a Serre functor S, and split idempotents …

Modules of infinite projective dimension

P Zhou, X Zhou - Rocky Mountain Journal of Mathematics, 2022 - projecteuclid.org
We characterize the modules of infinite projective dimension over the endomorphism
algebras of Oppermann–Thomas cluster-tilting objects X in (n+ 2)-angulated categories (𝒞 …

Ideal approximation in -angulated categories

L Tan, D Wang, T Zhao - arXiv preprint arXiv:2012.03398, 2020 - arxiv.org
In this paper, we study ideal approximation theory associated to almost $ n $-exact
structures in extension closed subcategories of $ n $-angulated categories. For $ n= 3$, an …

Support τn-tilting pairs

P Zhou, B Zhu - Journal of Algebra, 2023 - Elsevier
We introduce the higher version of Adachi-Iyama-Reiten's support τ-tilting pairs, which are
regarded as a generalization of maximal τ n-rigid pairs in the sense of Jacobsen-Jørgensen …
