Simple Yetter-Drinfeld modules over Generalized Liu algebras

Quantum Algebra 2026-03-25 v1 Representation Theory

Abstract

Let HH be a generalized Liu algebra over an algebraically closed field kk of characteristic zero. We prove that all simple Yetter-Drinfeld modules over HH are finite-dimensional and present an explicit classification of these modules. Moreover, we completely determine which of them admit a finite-dimensional Nichols algebra.
