Quotients of exact categories by cluster tilting subcategories as module categories

L Demonet, Y Liu - Journal of pure and applied algebra, 2013 - Elsevier
We prove that some subquotient categories of exact categories are abelian. This
generalizes a result by Koenig–Zhu in the case of (algebraic) triangulated categories. As a …

Weak cotorsion, τ-tilting and two-term categories

AB Buan, Y Zhou - Journal of Pure and Applied Algebra, 2024 - Elsevier
Motivated by its links to τ-tilting theory, we introduce left weak cotorsion pairs, as a
generalization of cotorsion pairs in module categories. Such pairs are also linked to co-t …

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 …

∞-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 …

Semibricks in extriangulated categories

L Wang, J Wei, H Zhang - Communications in Algebra, 2021 - Taylor & Francis
Let X be a semibrick in an extriangulated category C. Let T be the filtration subcategory
generated by X. We give a one-to-one correspondence between simple semibricks and …

properties in exact categories and extension-closed subcategories of triangulated …

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 …
