Title: The Tutte Symmetric Function

Speaker: Logan Crew Affiliation: University of Waterloo Zoom: Please email Emma Watson

Abstract:

The Tutte polynomial is one of the most celebrated and most well-studied graph functions, in part because it specializes to every graph polynomial with a linear deletion-contraction relation, such as the chromatic polynomial. In the 1990s, Stanley generalized the Tutte polynomial to a symmetric function, but at the cost of the deletion-contraction relation.
