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.
