Vortrag: Two braid group actions for Auslander algebras
Abstract: For the Auslander algebra of k[x]/(x^n), 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.
