Titre |
Scattering amplitudes and their geometric properties |
Résumé |
I will review a number of approaches to understanding properties of scattering
amplitudes and their applications. I will then focus on the relation of the
geometry of the kinematical space to the analytic behaviour of amplitudes as
functions on this space. We will take planar N=4 super Yang-Mills theory as a
guiding example, where cluster algebras of Grassmannian spaces play a central
role. This suggests a number of directions for generalising to non-supersymmetric
and non-planar cases. |
