Title: The Tutte polynomial and abelian quiver varieties


Abstract: The Tutte polynomial is a two-variable polynomial one may 
associate to a given graph. It's cool because it is universal among 
multiplicative graph invariants that respect certain deletion and 
contraction relations. Given a graph, one may also study an associated 
quiver algebra and count its modules over a finite field. Here we 
display a direct relation between the Tutte polynomial and this count of 
modules. The main result here is due to Hausel and Sturmfels but some 
methods may be new.

This joint work with Fernando Rodriguez Villegas and Anton Mellit.
