David Ploog (Hannover), Two braid group actions for Auslander algebras
For the Auslander algebra of k[x]/(xn), I explain how spherical
modules and full exceptional sequences of modules can be classified in a
beautiful combinatorial manner. There are a left and a right action of the
symmetric group on these sequences and I show how to categorify these.
