injectives I \mathcalI, and let be a contravariantly finite rigid subcategory of which contains P …

On support τ-tilting modules over endomorphism algebras of rigid objects

W Chang, J Zhang, B Zhu - Acta Mathematica Sinica, English Series, 2015 - Springer
Abstract We consider a Krull–Schmidt, Hom-finite, 2-Calabi–Yau triangulated category with
a basic rigid object T, and show a bijection between the set of isomorphism classes of basic …

Relative rigid objects in extriangulated categories

Y Liu, P Zhou - Journal of Pure and Applied Algebra, 2022 - Elsevier
In this paper, we study a close relationship between relative cluster tilting theory in
extriangulated categories and τ-tilting theory in module categories. Our main results show …

On the relation between maximal rigid objects and τ-tilting modules

P Liu, Y Xie - Colloquium Mathematicum, 2016 - infona.pl
This note compares τ-tilting modules and maximal rigid objects in the context of 2-Calabi-
Yau triangulated categories. Let 𝓒 be a 2-Calabi-Yau triangulated category with suspension …

Two-term relative cluster tilting subcategories, τ-tilting modules and silting subcategories

P Zhou, B Zhu - Journal of Pure and Applied Algebra, 2020 - Elsevier
Let C be a triangulated category with shift functor [1] and R a rigid subcategory of C. We
introduce the notions of two-term R [1]-rigid subcategories, two-term (weak) R [1]-cluster …

𝜏-tilting theory in abelian categories

Y Liu, P Zhou - Proceedings of the American Mathematical Society, 2022 - ams.org
Let $\mathcal {A} $ be a Hom-finite abelian category with enough projectives. In this note,
we show that any covariantly finite $\tau $-rigid subcategory is contained in a support $\tau …

Intermediate co-t-structures, two-term silting objects, τ-tilting modules, and torsion classes

O Iyama, P Jørgensen, D Yang - Algebra & Number Theory, 2014 - msp.org
Abstract If (A, B) and (A′, B′) are co-t-structures of a triangulated category, then (A′, B′)
is called intermediate if A⊆ A′⊆ Σ A. Our main results show that intermediate co-t …

Image-extension-closed subcategories of module categories of hereditary algebras

H Enomoto, A Sakai - Journal of Pure and Applied Algebra, 2023 - Elsevier
We study IE-closed subcategories of a module category, subcategories which are closed
under taking Images and Extensions. We investigate the relation between IE-closed …

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 …
