Joint Seminar “Quantum Field Theory” and “Modern Mathematical Physics”
Date and Time: Wednesday, 6 June 2018, at 11:00 AM
Venue: Blokhintsev Hall (4th floor), Bogoliubov Laboratory of Theoretical Physics
Seminar topic: “Motivic approach to the evaluation of Feynman integrals”
Speaker: Pierre Vanhove (IPhT, Saclay)
Abstract:
In this talk I will present a way to evaluate Feynman integral making use of the algebraic geometry defined by the graph polynomial. I will explain in what sense Feynman integral are period integrals, and how this point of view allows to derive their differential equation and provide new way of evaluating these integrals.
