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…

q,t-Fuss-Catalan numbers for complex 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 S_n. We generalize this construction to (finite)…

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…
