Recollements arising from cotorsion pairs on extriangulated categories

Y Hu, P Zhou - Frontiers of Mathematics in China, 2021 - Springer
This paper is devoted to constructing some recollements of additive categories associated to
concentric twin cotorsion pairs on an extriangulated category. As an application, this result …

-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 …

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 …

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 …

Dimensions and cotorsion pairs in recollements of extriangulated categories

X Ma, P Zhou - arXiv preprint arXiv:2310.11172, 2023 - arxiv.org
Let $(\mathcal A,\mathcal B,\mathcal C) $ be a recollement of extriangulated categories. In
this paper, we provide bounds on the coresolution dimensions of the subcategories involved …

Hereditary cotorsion pairs on extriangulated subcategories

Y Liu, P Zhou - arXiv preprint arXiv:2012.06997, 2020 - arxiv.org
Let $\mathcal B $ be an extriangulated category with enough projectives and enough
injectives. We define a proper $ m $-term subcategory $\mathcal G $ on $\mathcal B …

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 …

Hereditary cotorsion pairs and silting subcategories in extriangulated categories

T Adachi, M Tsukamoto - Journal of Algebra, 2022 - Elsevier
In this paper, we study (complete) cotorsion pairs in extriangulated categories. First, we
study a relationship between an interval of the poset of cotorsion pairs and the poset of …

Abelian hearts of twin cotorsion pairs on extriangulated categories

Q Huang, P Zhou - Algebra Colloquium, 2023 - World Scientific
It was shown recently that the heart of a twin cotorsion pair on an extriangulated category is
semi-abelian. In this article, we consider a special class of hearts of twin cotorsion pairs …
