Anatomy of the amplituhedron
Daniele Galloni
(Durham)
Abstract:
I will present this very recently proposed geometric object, conjectured to give the N=4 SYM scattering amplitudes at all orders , and illustrate the techniques used to fully explore its structure. In so doing I will give firm nontrivial evidence to the amplituhedron conjecture.

Tensor Models and Renormalization
Joseph Ben Geloun
(AEI Golm)
Abstract:
A review will be provided on the renormalization program for
the so-called Tensor Models for Quantum Gravity. These are non local field theories extending both the matrix models, a successful framework in statistical mechanics
applied to 2D physics, and the Grosse-Wulkenhaar model in the matrix basis
arising in Noncommuting Neometry. We will emphasize the Multi-scale renormalization
but also report recent results on the Functional Renormalization Group Approach for these class of models.
