Title: Cluster structures in N=4 SYM amplitudes
Abstract: A surprising property of planar N=4 SYM amplitudes these amplitudes is that they satisfy mysterious connections with cluster algebras. These connections are both interesting theoretically, and play a crucial role in calculating the amplitudes. In my talk I will describe the amplituhedron, the non-negative Grassmannian on which it is built. I will then explain one of the central relations with clusters, its proof, and a recent conjectural generalization in the language of operads. Based on joint works with Chaim Even Zohar, Tsviqa Lakrec, Matteo Parisi, Melissa Sherman Bennett and Lauren Williams.
