Polytopes, supersymmetry, and integrable systems

Abstract

We review some links between Lie-theoretic polytopes and field theories in physics, which were proposed in the 1990's. A basic ingredient is the Coxeter Plane, whose relation to integrable systems and the Stokes Phenomenon has only recently come to light. We use this to give a systematic mathematical treatment, which gives further support to the physical proposals. This article is based on a talk which was scheduled to be given at the workshop "Representations of Discrete Groups and Geometric Topology on Manifolds", Josai University, 12-13 March 2020.
