Symmetry and Graph Coloring: Algebraic and Combinatorial Mysteries
📄 ABSTRACT / RÉSUMÉ
The study of proper colorings of graphs is a longstanding and important area in mathematics. The Four Color theorem for planar graphs is one famous success, and this simple problem in cartography launched a vast theory leading to many concrete applications, as well as to the algebraic study of chromatic polynomials and symmetric functions, which also arise in the geometry of Hessenberg varieties.
