Ehrhart Series of Polytopes Related to Symmetric Doubly-Stochastic Matrices
Robert Davis
In Ehrhart theory, the -vector of a rational polytope often provide insights into properties of the polytope that may be otherwise obscured. As an example, the Birkhoff polyto…

Ehrhart series, unimodality, and integrally closed reflexive polytopes
Benjamin Braun, Robert Davis
An interesting open problem in Ehrhart theory is to classify those lattice polytopes having a unimodal -vector. Although various sufficient conditions have been found, necessa…
