From Feynman diagrams to the Amplituhedron

In this talk, I will go over (in a way that is friendly for mathematicians) the calculation of the tree-level Yang-Mills NMHV scattering amplitude for six gluons (that is, of the simplest amplitude for which the amplituhderon makes sense). In particular, we will see that Feynman diagrams and computing the canonical form of the n =6, k=1, m=4 Amplituhedron give the same result for the amplitude. This is based on joint work with Shounak De, Marcus Spradlin and Anastasia Volovich.
