Arithmetic Study Group: Overview

Presented by Herbert Gangl, Durham

1 November 2007 14:15 in CM219

Physicists and mathematicians alike have encountered "periods" (arising from integrating an algebraic integrand against an algebraically defined domain), on the one hand from considering Feynman graphs, and on the other hand from associating interesting invariants to "motives".
This term in the seminar series, we would like to understand work that has been done relating the two--rather different--points of view. As a main example, Bloch-Esnault-Kreimer have linked the period zeta(3) arising from the "wheel of spokes graph" in physics to algebraic-geometric constructions.
