Renormalization via algebraic geometry
Prof. Spencer Bloch, PhD
31 May 2011, 16:00 – 17:00

The theory of limiting mixed hodge structures in algebraic geometry yields a canonical renormalization scheme for feynman integrals with at worst logarithmic divergences. I will talk about a joint paper with Dirk Kreimer working out the details in the case of trivial masses and momenta. From this viewpoint, Feynman rules are naturally interpreted as 1-parameter subgroups in the algebraic group associated to the Hopf algebra of graphs.
