Tilting objects in triangulated categories

Y Hu, H Yao, X Fu - Communications in Algebra, 2020 - Taylor & Francis
Based on Beligiannis's theory in [Beligiannis, A.(2000). Relative homological algebra and
purity in triangulated categories. J. Algebra 227 (1): 268–361], we introduce and study E …

Tilting subcategories in extriangulated categories

B Zhu, X Zhuang - Frontiers of Mathematics in China, 2020 - Springer
Extriangulated category was introduced by H. Nakaoka and Y. Palu to give a unification of
properties in exact categories and triangulated categories. A notion of tilting (resp., cotilting) …

[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 …

[PDF][PDF] Left Frobenius pairs, cotorsion pairs and weak Auslander-Buchweitz contexts in triangulated categories

X Ma, T Zhao, Z Huang - Algebra Colloq, 2021 - maths.nju.edu.cn
Let T be a triangulated category with a proper class ξ of triangles. We introduce the notions
of left Frobenius pairs, left (n-) cotorsion pairs and left (weak) Auslander-Buchweitz contexts …

Proper classes and Gorensteinness in extriangulated categories

J Hu, D Zhang, P Zhou - Journal of algebra, 2020 - Elsevier
Extriangulated categories were introduced by Nakaoka and Palu as a simultaneous
generalization of exact categories and triangulated categories. A notion of proper class in an …

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 …

Right triangulated categories with right semi-equivalences

I Assem, A Beligiannis… - CMS Conference …, 1998 - books.google.com
We show that a right triangulated category is best behaved when its shift satisfies conditions
making it what we call a right semi-equivalence. We consider right triangulated categories …

General heart construction on a triangulated category (II): Associated homological functor

N Abe, H Nakaoka - Applied Categorical Structures, 2012 - Springer
In the preceding part (I) of this paper, we showed that for any torsion pair (ie, t-structure
without the shift-closedness) in a triangulated category, there is an associated abelian …

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 …

[PDF][PDF] Ghost-tilting objects in triangulated categories

WZ Yang, B Zhu - arXiv preprint arXiv:1504.00093, 2015 - researchgate.net
Assume that D is a Krull-Schmidt, Hom-finite triangulated category with a Serre functor and a
cluster-tilting object T. We introduce the notion of ghost-tilting objects, and T [1]-tilting objects …
