Graphs and Matroids Seminar: Edward Lee

Title: Circle Graph Obstructions

Speaker: Edward Lee
Affiliation: University of Waterloo
Room: MC 5479

Abstract:

A circle graph is the intersection graph of a set of chords drawn on a circle.  We present a graphic proof of Bouchet's characterization of the class of circle graphs.
