Scattering equations: from projective spaces to tropical grassmannians

Abstract We introduce a natural generalization of the scattering equations, which connect the space of Mandelstam invariants to that of points on ℂℙ1, to higher-dimensional projective spaces ℂℙ k − 1. The standard, k = 2 Mandelstam invariants, s ab , are generalized to completely symmetric tensors s...
