Julian Külshammer (Kiel), Auslander-Reiten theory of Frobenius-Lusztig kernels.

Abstract:
In 1995 Erdmann showed that the Auslander-Reiten components of all wild group algebras have the same tree class. The Frobenius-Lusztig kernels form a class of finite dimensional symmetric Hopf algebras, which are not cocommutative and in most cases wild. In this talk we provide a survey on combinatorial and geometric methods to prove a weak analogue of Erdmann's result for this class of algebras: The only possible tree classes are the three infinite Dynkin diagrams and one tree class seems to be most prominent.
