Projective Geometry and Amplitudes

by Mattias Sjö (Lund U.)


Projective geometry is a fascinating branch of mathematics with a broad range of applications. Among other things, a projective treatment renders many classical Euclidean problems almost trivial. Presented here is an excerpt of Nima Arkani-Hamed's somewhat unexpected application onto the theory of scattering amplitudes, which, via a foray into canonical differential forms, leads to concepts such as the associahedron and amplituhedron.

Here is a link to recordings of the lectures upon which the seminar was based:
