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.
