Quotients of exact categories by pseudo-cluster tilting subcategories

Jie Xu, Yuefei Zheng

We introduce the concept of a pseudo-cluster tilting subcategory from the viewpoint of the fact that the quotient of an exact category by a cluster tilting subcategory is an abelia…

2-recollements of singualrity categories and Gorenstein defect categories over triangular matrix algebras

Huanhuan Li, Dandan Yang, Yuefei Zheng +1

Let $T = (A, M, 0, B)$ be a triangular matrix algebra with its corner algebras $A$ and $B$ Artinian and $_{A} M_{B}$ an $A$ - $B$ -bimodule. The 2-recollement structures for singularity categor…

When the Schur functor induces a triangle-equivalence between Gorenstein defect categories

Huanhuan Li, Jiangsheng Hu, Yuefei Zheng

Let $R$ be an Artin algebra and $e$ an idempotent of $R$ . Assume that $Tor_{i}^{e R e} (R e, G) = 0$ for any $G \in GProj e R e$ and $i$ sufficiently large. Necessary and sufficient…

Gorenstein projective modules and recollements over triangular matrix rings

Huanhuan Li, Yuefei Zheng, Jiangsheng Hu +1

Let $T = (R M 0 S)$ be a triangular matrix ring with $R$ and $S$ rings and $_{R} M_{S}$ an $R$ - $S$ -bimodule. We describe Gorenstein project…

On Pure Derived Categories

Yuefei Zheng, Zhaoyong Huang

We investigate the properties of pure derived categories of module categories, and show that pure derived categories share many nice properties of classical derived categories. In…

Auslander-Reiten Triangles in Homotopy Categories

Yuefei Zheng, Zhaoyong Huang

Let $A$ be an artin algebra. We show that the bounded homotopy category of finitely generated right $A$ -modules has Auslander-Reiten triangles. Two applications are given: (1) we p…
