The Amplituhedron is a geometric object discovered recently by Arkani-Hamed and Trnka,
that provides a completely new direction for calculating scattering amplitudes in
quantum field theory (QFT).
We define a tropical analogue of this object, the tropicial amplituhedron and study its structure and boundaries. It can be considered as both the tropical limit of the amplituhedron and a generalization of the tropical positive Grassmannian. |
