Weborder series are related to the Ehrhart series of Poly(P), or its h∗-vector, by a change of basis and a shift of degree. From the point of view of Ehrhart theory there are several works characterizing h∗-vectors [2, 17, 27] and f∗-vectors [7] of polytopes. We instead study Ehrhart series of order polytopes.
