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 be a triangular matrix algebra with its corner algebras and Artinian and an --bimodule. The 2-recollement structures for singularity categor…
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 be an artin algebra. We show that the bounded homotopy category of finitely generated right -modules has Auslander-Reiten triangles. Two applications are given: (1) we p…
