Rickard's question on standard derived equivalences
Wei Hu, Changchang Xi, Jin Zhang
In 1991 Rickard asked whether every derived equivalence of algebras over a common field is standard. We construct a series of examples of non-standard derived equivalences, and thu…
Higher cluster tilting objects in locally finite triangulated categories
Qi Bin, Yifu Han, Wei Hu
We study higher cluster tilting objects through covering functors from derived categories of hereditary algebras. The covering formalism reduces the existence problem to the equiva…
Level-rank dualities and moving vectors
Wei Hu, Feiyue Huang, Yanbo Li +1
Duality relations between Lie algebras are a significant phenomenon in Lie algebra representation theory, with level-rank duality as a famous example. Level-rank dualities for affi…
Rigidity degrees of indecomposable modules over representation-finite self-injective algebras
Wei Hu, Xiaojuan Yin
The rigidity degree of a generator-cogenerator determines the dominant dimension of its endomorphism algebra, and is closely related to a recently introduced homological dimension…
Singular equivalences and Auslander-Reiten conjecture
Yiping Chen, Wei Hu, Yongyun Qin +1
Auslander-Reiten conjecture, which says that an Artin algebra does not have any non-projective generator with vanishing self-extensions in all positive degrees, is shown to be inva…
Zero action determined modules for associative algebras
Wei Hu, Zhankui Xiao
Let be a unital associative algebra over a field and be a unital left -module. The module is called zero action determined if every bilinear map $f: A\times V\ri…
