The Combinatorial Structure of Moment Polytopes

Abstract: I will discuss a problem that lies in the intersection of symplectic geometry and combinatorics. The symmetries of a symplectic manifold are reflected in its moment polytope. There is a dictionary translating the geometry into combinatorics, and vice versa. I will start with the definition of a polytope, describe enough symplectic geometry to motivate the moment polytope, and then I will discuss several of the dictionary entries.
