Feynman graphs, Periods and Polylogarithms: Quantum electrodynamics and recursive structures

Presented by Dirk Kreimer, IHES Paris and Boston University

9 January 2008 16:00 in CM105

We specialize to quantum electrodynamics (QED) as a gauge theory, study ideals and co-ideals to understand the Ward identities and use all the previous lectures to boil the equations of motion down to a single ordinary differential equation which determines the beta function of QED in terms of a certain series in periods.
