Recollements and n-cluster tilting subcategories

T Long, X Zhang, Y Zhou - Communications in Algebra, 2024 - Taylor & Francis
In this paper, we study the relationship among three n-cluster tilting subcategories of
triangulated categories in a recollement. Let (D′, D, D ″) be a recollement of triangulated …

From recollement of triangulated categories to recollement of abelian categories

YN Lin, MX Wang - Science China Mathematics, 2010 - Springer
In this paper, we prove that if a triangulated category D admits a recollement relative to
triangulated categories D'and D'', then the abelian category D/T admits a recollement …

Cotorsion pairs in a recollement of triangulated categories

J Chen - Communications in Algebra, 2013 - Taylor & Francis
In the present article, we study the relationship of cotorsion pairs among three triangulated
categories in a recollement. We show that if a triangulated category 𝒟 admits a recollement …

-cotorsion pairs and recollements of extriangulated categories

J He, J He - arXiv preprint arXiv:2403.12673, 2024 - arxiv.org
In this article, we prove that if $(\mathcal A,\mathcal B,\mathcal C) $ is a recollement of
extriangulated categories, then $ n $-cotorsion pairs in $\mathcal A $ and $\mathcal C $ can …

Abelian quotients of extriangulated categories

J He, P Zhou - Proceedings-Mathematical Sciences, 2019 - Springer
We prove that certain subquotient categories of extriangulated categories are abelian. As a
particular case, if an extriangulated category CC has a cluster-tilting subcategory XX, then …

A bijection between tilting subcategories and cotorsion pairs in extriangulated categories

Z Zhu, J Wei - arXiv preprint arXiv:2403.03546, 2024 - arxiv.org
Let $\mathscr {C} $ be an extriangulated category with enough projectives and injectives.
We give a new definition of tilting subcategories of $\mathscr {C} $ and prove it coincides …

∞-Tilting Subcategories in Extriangulated Categories

Z Zhang, J Wei, S Wang - Chinese Annals of Mathematics, Series B, 2024 - Springer
In this paper, the authors introduce a new definition of∞-tilting (resp. cotilting) subcategories
with infinite projective dimensions (resp. injective dimensions) in an extriangulated category …

Torsion pairs and recollements of extriangulated categories

J He, Y Hu, P Zhou - Communications in Algebra, 2022 - Taylor & Francis
In this article, we prove that if (A, B, C) is a recollement of extriangulated categories, then
torsion pairs in A and C can induce torsion pairs in B, and the converse holds under natural …

Recollements of extriangulated categories

L Wang, J Wei, H Zhang - arXiv preprint arXiv:2012.03258, 2020 - arxiv.org
We give a simultaneous generalization of recollements of abelian categories and
triangulated categories, which we call recollements of extriangulated categories. For a …
