Beyond positivity in Ehrhart Theory

Abstract

We study semigroup algebras arising from lattice polytopes, compute their volume polynomials (particularizing work of Hochster), and establish strong Lefschetz properties (generalizing work of the first three authors). This resolves several conjectures concerning unimodality properties of the hh^\ast-polynomial of lattice polytopes arising within Ehrhart theory.
