Amplituhedron cells and Stanley symmetric functions
Abstract
The amplituhedron was recently introduced in the study of scattering amplitudes in N=4 super Yang-Mills. We compute the cohomology class of a tree amplituhedron subvariety of the Grassmannian to be the truncation of an affine Stanley symmetric function.
