Cyclic Sieving of Multisets with Bounded Multiplicity and the Frobenius Coin Problem
Drew Armstrong
The two subjects in the title are related via the specialization of symmetric polynomials at roots of unity. Let be a symmetric pol…
Lattice Points and Rational -Catalan Numbers
Drew Armstrong
For each pair of coprime integers and we have a rational -Catalan number . It is known that this is a polynomial in $…
The Waldspurger Transform of Permutations and Alternating Sign Matrices
James McKeown
In 2005 J.L. Waldspurger proved the following theorem: given a finite real reflection group , the closed positive root cone is tiled by the images of the open weight cone under…
Euler characteristic of the truncated order complex of generalized noncrossing partitions
Drew Armstrong, Christian Krattenthaler
The purpose of this note is to complete the study, begun in the first author's PhD thesis, of the topology of the poset of generalized noncrossing partitions associated to real ref…
