Short introductory talks.

The study of Feynman integrals in high-energy physics leads to an interesting family of complex algebraic hypersurfaces indexed by graphs.  Their geometry and topology is a reflection of the underlying combinatorics of matroids, but apparently in intricate and mostly unknown ways.  Can a physically motivated construction provide a new tool in matroid combinatorics?
