SUMMARY:Tutte polynomials of graphs and symplectic duality - Ben Davison\,

DESCRIPTION:The Tutte polynomial of a graph is a two-variable polynomial\,
  which is the universal polynomial satisfying deletion contraction recursi
 on.  In this talk I will explain how this polynomial arises from consideri
 ng the cohomology of hypertoric varieties (which I'll introduce) along wit
 h the two (not one!) filtrations by cohomological degree\, coming from sym
 plectic duality (which I will also introduce).
