Exceptional sequences for the Auslander algebra of the fat point

A talk in the 'Seminar Representation Theory of Algebras' series by
David Ploog from Berlin
Abstract: This algebra is well-known in representation-theory. We classify spherical modules and full exceptional sequences over this algebra. There are combinatorial left/right symmetric group actions on these sequences. We categorify both of these, using spherical twists and right mutations. All of this can be nicely visualised using worm diagrams.
