摘要：The Dynkin Diagram and the Stiefel Diagram are ”visualizations” of Lie groups (or their root systems) which are very familiar to geometers and topologists. We propose an ”enhanced” Coxeter Plane as a third visualization. This has a purely Lie-theoretic definition, but it arises most naturally from a certain isomonodromic family of meromorphic connections, constructed as a special case of the Toda equations - an integrable system. This is joint work with Nan-Kuo Ho.
