Both of these are known to grow as polynomials. Generally, the former are subsets of the latter. In this paper, we will see that sumsets occupy all the central lattice points in convex hulls, giving us a kind of approximation to lattice points in polytopes.7 pagesNumber TheoryCombinatorics11H06, 11P21 (Primary) 52B20 (Secondary)text
