SMRI Seminar: Lam -- Positive geometry and scattering amplitudes

Speaker: Thomas Lam, University of Michigan 

Abstract: Positive geometry is a new field developing at the
intersection of combinatorial geometry in mathematics and scattering
amplitudes in physics.  Scattering amplitudes are functions that
predict the outcome of particle physics experiments.  The goal of
positive geometry is to recover these functions using a mixture of
combinatorics and geometry.  I will give an introduction to the
subject.
