LetPbe a lattice polytope with the-vector. In this note we show that if, then the Ehrhart ringis generated in degrees at mostas a-algebra. In particular, ifand, thenPis IDP. To see this, we show the corresponding statement for semi-standard graded Cohen–Macaulay domains over algebraically closed fields.
