Pure Maths Colloquium: Motives arising from physics
1 March 2010 16:15 in CM107
This talk is intended for a general mathematical audience. I will try to explain how basic scattering matrix computations in physics (one loop Feynman amplitudes) give rise to dilogarithm motives. If time permits, I will explain a bit about dispersion relations and Cutkowsky rules in physics and what they have to do with monodromy in mathematics.
