Title:  Flow polytope volumes and Ehrhart theory

Abstract:

The first half of this talk will be a survey regarding flow polytopes and their volumes. The Ehrhart h*-polynomial is a refinement of the volume of a lattice polytope. In the second half of this talk, I will discuss recent joint work with K. Bruegge, R. Davis and D. Hanely regarding Ehrhart h*-polynomials of a class of acyclic directed graphs that we call extensions of bipartite graphs
