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…

On bijections between 231-avoiding permutations and Dyck paths
Christian Stump
We construct a bijection between 231-avoiding permutations and Dyck paths that sends the sum of the major index and the inverse major index of a 231-avoiding permutation to the maj…
