The equivariant Ehrhart theory of the permutahedron

The Arithmetic of Coxeter Permutahedra

“…Proposition 3.1 is an intermediate step that may be of independent interest: it describes the Ehrhart theory of a rational translate of an integral zonotope. This result was used in [3] to compute the equivariant Ehrhart theory of the permutahedron.…”

“…In [3], Proposition 3.1 is used to describe the equivariant Ehrhart theory of the permutahedron and prove a series of conjectures due to Stapledon [19] in this special case.…”
