Title: Scattering Amplitudes, Positive Geometry and the Amplituhedron
Abstract: I will review the status of (loop level) scattering amplitudes in N=4 super Yang-Mills theory for n $greater than$ 7, where the corresponding Grassmannian cluster algebras Gr(4,n) are infinite and novel features emerge, notably the appearance of certain “marginally positive” algebraic functions of cluster variables.*
