Abstract:
We will discuss the relation between the Coxeter complex of a Weyl group $W$ and the action of $W$ on a suitable quotient $R$ of the ring of super-polynomials. The elements of the Coxeter complex can be viewed as certain ordered set partitions. Our goal is to find combinatorial statistics on these objects that realise the Hilbert series of the graded representation $R$.
