Proof of Chapoton's conjecture on Newton polygons of $q$-Ehrhart polynomials

Combinatorics 2018-06-05 v2

Abstract

Recently, Chapoton found a qq-analog of Ehrhart polynomials, which are polynomials in xx whose coefficients are rational functions in qq. Chapoton conjectured the shape of the Newton polygon of the numerator of the qq-Ehrhart polynomial of an order polytope. In this paper, we prove Chapoton's conjecture.
