From amplitudes to representations
Prof. Dr. Francis Brown (IHES / Oxford University)
7.7.2015, 17:00 Uhr – 18:00 Uhr
Some deep ideas in algebraic geometry lead one to view certain numbers and functions as representations of a group.
For example, the number pi corresponds to a 1-dimensional representation, and values of the Riemann zeta function zeta(n) correspond to 1 or 2 dimensional representations depending if n is odd or even.
In this talk Prof. Dr. Francis Brown will explain how to attach a representation to a Feynman amplitude. This reveals many hidden structures amongst amplitudes - for example, to any amplitude there are notions of weights, symbols, and Galois conjugates.
