Mathematical Physics Seminar
The seminars take place on Tuesday lunchtimes at 2:00 pm (mostly internal speakers) and Thursday afternoons from 4:15 pm (mostly external speakers, and preceded by coffee/tea from 4pm), in the relaxed atmosphere of Room G/109 in James College Nucleus. The typical length of the talks is about 1 hour.

Mathematical Physics Seminar
Date and time:
April 24, 2014, 16:15  17:30
Speaker:
Susama Agarwala (Oxford)
In this talk, I describe a candidate renormalization group for a perturbative Quantum Field Theory, following the constructiions of Connes, Marcolli, Kreimer, et. al. Then I show that the energy scale dependence of the regularized theory is defined by a connection of the principal fibre bundle defined by the renormalization group. This connection relates different energy scale dependencies one gets from different regularization methods.
