Quasi-abelian quotients in extriangulated categories

Yu Liu, Yu-Zhe Liu, Panyue Zhou

Let $(E, E, s)$ be an extriangulated category. Motivated by the theory of hereditary algebras, we introduce the notion of a hereditary-type subcategor…

Mutation of $n$ -cotorsion pairs in extriangulated categories

Huimin Chang, Yu Liu, Panyue Zhou

In this article, we introduce the notion of $n$ -cotorsion pairs in extriangulated categories, which extends both the cotorsion pairs established by Nakaoka and Palu and the $n$ -cot…

Relative cluster tilting theory and $I ¨ $ -tilting theory

Yu Liu, Jixing Pan, Panyue Zhou

Let $C$ be a Krull-Schmidt triangulated category with shift functor $[1]$ and $R$ be a rigid subcategory of $C$ . We are concerned with the mutation of tw…
