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 …

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 …

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 …

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 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 …

[HTML][HTML] Hearts of twin cotorsion pairs on extriangulated categories

Y Liu, H Nakaoka - Journal of Algebra, 2019 - Elsevier
In this article, we study the heart of a cotorsion pairs on an exact category and a triangulated
category in a unified method, by means of the notion of an extriangulated category. We …

Tilting objects in triangulated categories
