Title:
Chromatic polynomials of signed Petersen graphs

Speaker:
Erika Meza

Abstract:
T. Zaslavsky proved that there are essentially six signed versions of the famous Petersen graph. (Look here for an introduction to signed graphs.) He conjectures that they all have different chromatic polynomials. We will try to compute the latter, e.g., using A. Van Herick's IOP software.
