Derived discrete Hopf algebras with the Chevalley property

Quantum Algebra 2024-12-12 v1 Representation Theory

Abstract

We try to classify Hopf algebras with the Chevalley property according to their derived representation type. We show that a finite-dimensional indecomposable non-semisimple Hopf algebra HH with the Chevalley property is derived discrete if and only if it is isomorphic to (A(n,2,μ,1))(A(n, 2, \mu, -1))^*. Besides, we give a description for the indecomposable objects in Db((A(n,2,μ,1)))\mathcal{D}^b((A(n, 2, \mu, -1))^*) and determine their tensor products.
