Counting the number of elements in the mutation classes of \tilde{A}_n-quivers
Janine Bastian, Thomas Prellberg, Martin Rubey +1
In this article we prove explicit formulae for the number of non-isomorphic cluster-tilted algebras of type \tilde{A}_n in the derived equivalence classes. In particular, we obtain…

Crossings and nestings in set partitions of classical types
Martin Rubey, Christian Stump
In this article, we investigate bijections on various classes of set partitions of classical types that preserve openers and closers. On the one hand we present bijections that int…

q,t-Fuss-Catalan numbers for finite reflection groups
Christian Stump
In type A, the q,t-Fuss-Catalan numbers can be defined as a bigraded Hilbert series of a module associated to the symmetric group. We generalize this construction to (finite) compl…
