Abstract: Abstract The amplituhedron determines scattering amplitudes in planar $$ \mathcal{N} $$ N = 4 super Yang-Mills by a single “positive geometry” in the space of kinematic and loop variables. We study a closely related definition… read more here.

Abstract: In this paper we provide a formula for the canonical differential form of the hypersimplex Δ_{k,n} for all n and k. We also study the generalization of the momentum amplituhedron M_{n,k} to m=2, which has… read more here.
