Graphs, links, and duality on surfaces
by
Slava Krushkal
University of Virginia

I will introduce a polynomial invariant of graphs on surfaces, generalizing the Tutte polynomial. This invariant satisfies a natural duality property, and it is closely related to the Bollobas-Riordan polynomial. I will also discuss a generalization of the Jones polynomial and Kauffman bracket for links in thickened surfaces, and their relation with the graph polynomial.
