A quiver approach to quasi-quantum groups with the Chevalley property

Jing Yu

In this paper, we develop a quiver approach to coquasi-Hopf algebras with the dual Chevalley property. We introduce a modified generalized path coalgebra $\Bbbk(\mathrm{Q},\mathcal…

Simple Yetter-Drinfeld modules over Generalized Liu algebras

Xiangjun Zhen, Gongxiang Liu, Jing Yu

Let be a generalized Liu algebra over an algebraically closed field of characteristic zero. We prove that all simple Yetter-Drinfeld modules over are finite-dimensional…

Coquasitriangular structures on Hopf algebras constructed via abelian extensions

Jing Yu, Xiangjun Zhen

The aim of this paper is to study coquasitriangular structures on a class of cosemisimple Hopf algebras of the form , constructed as abelian extensions…

Hopf algebras with the dual Chevalley property of discrete corepresentation type

Jing Yu, Gongxiang Liu

We try to classify Hopf algebras with the dual Chevalley property of discrete corepresentation type over an algebraically closed field with characteristic 0. For such Hop…

Simple Yetter-Drinfeld modules over infinite-dimensional Taft algebras

Xiangjun Zhen, Gongxiang Liu, Jing Yu

Let H be an infinite-dimensional Taft algebra over an algebraically closed field k of characteristic 0. We find all the simple Yetter-Drinfeld modules V over H, and classifies thos…
