Homological properties of quantum groups governed by small quantum groups
Yimin Huang, Tiancheng Qi, Quanshui Wu +1
We develop a general characteristic-free framework for studying the homological properties of a broad class of module-finite Hopf algebras. This framework makes it possible to redu…

Chevalley property of module-finite Hopf algebras and discriminant ideals
Yimin Huang, Tiancheng Qi, Quanshui Wu +1
In this paper, we study the Chevalley property of Cayley-Hamilton Hopf algebras in the sense of De Concini-Procesi-Reshetikhin-Rosso using discriminant ideals. For any affine Cayle…
