Unconditional Reflexive Polytopes
Florian Kohl (Aalto)
Abstract: A convex body is unconditional if it is symmetric with respect to reflections in all coordinate hyperplanes. In this talk, we investigate unconditional lattice polytopes with respect to geometric, combinatorial, and algebraic properties. In particular, we characterize unconditional reflexive polytopes in terms of perfect graphs. As a prime example, we study a type-$B$ analogue of the Birkhoff polytope. This talk is based on joint work with McCabe Olsen and Raman Sanyal.
