# ehrhartRing -- Ehrhart ring

## Description

The input of this function is considered as vertices of a lattice polytope P. The Ehrhart ring of a (lattice) polytope P is the monoid algebra defined by the monoid of lattice points in the cone over the polytope P; see Bruns and Gubeladze, Polytopes, Rings, and K-theory, Springer 2009, pp. 228, 229. The function computes the lattice points of the polytope and its Ehrhart ring.

## Ways to use ehrhartRing:

- ehrhartRing(List) -- Ehrhart ring
- ehrhartRing(List,RingElement) -- Ehrhart ring

## For the programmer

The object ehrhartRing is a method function with options.
