The positive Grassmannian, the amplituhedron, and cluster algebras
Mon, May. 15th 2023, 11:00-12:00
Salle Claude Itzykson, Bât. 774, Orme des Merisiers
I will give a gentle introduction to the positive Grassmannian and the amplituhedron, a geometric object that was introduced in the context of scattering amplitudes in N=4 super Yang Mills. I'll then explain some of the connections of the amplituhedron to combinatorics and to cluster algebras.
