Ozgur Ceyhan: Feynman integrals, motives of configuration spaces, and multiple zeta values.

This talk is devoted to give a description of differential forms representing Feynman  amplitudes in configuration spaces of Feynman graphs, and their regularization and  evaluation techniques, for suitable chains of integration. In the end, we will show that  they give rise to periods of mixed Tate motives and therefore they are Q[1/2\pi i]  linear combinations of multiple zeta values.
