Positivity theorems for solid-angle polynomials
Matthias Beck, Sinai Robins, Steven V Sam
For a lattice polytope P, define A_P(t) as the sum of the solid angles of all the integer points in the dilate tP. Ehrhart and Macdonald proved that A_P(t) is a polynomial in the p…

A finite calculus approach to Ehrhart polynomials
Steven V Sam, Kevin M. Woods
A rational polytope is the convex hull of a finite set of points in with rational coordinates. Given a rational polytope , Ehrhart proved that, for $t\in\Z…
