Let A = (A 1 , . . . , Aq) be a q-tuple of finite sets of integers. Associated to every q-tuple of nonnegative integers h = (h 1 , . . . , hq) is the linear formconsists of all elements of this sumset with at least t representations. The structure of the set (h • A) (t) is computed for all sufficiently large h i .

We consider a finite set of lattice points and their convex hull. The author previously gave a geometric proof that the sumsets of these lattice points take over the central regions of dilated convex hulls, thus revealing an interesting connection between additive number theory and geometry. In this paper, we will see an algebraic proof of this fact when the convex hull of points is a simplex, exploring the connection between additive number theory and geometry further.
“…. , h r sufficiently large, the structure of this "linear form" has also been completely determined (Han, Kirfel, and Nathanson [2]), and its cardinality is a linear function of h 1 , . .…”
Let S be an abelian semigroup, and A a finite subset of S. The sumset hA consists of all sums of h elements of A, with repetitions allowed. Let |hA| denote the cardinality of hA. Elementary lattice point arguments are used to prove that an arbitrary abelian semigroup has polynomial growth, that is, there exists a polynomial p(t) such that |hA| = p(h) for all sufficiently large h. Lattice point counting is also used to prove that sumsets of the form h1A1 + • • • + hrAr have multivariate polynomial growth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
