Proudfoot-Speyer degenerations of scattering equations
- Barbara Betti (MPI MiS, Leipzig)
Abstract
We study scattering equations of hyperplane arrangements from the perspective of combinatorial commutative algebra and numerical algebraic geometry. We formulate the problem as linear equations on a reciprocal linear space and develop a degeneration-based homotopy algorithm for solving them. We investigate the Hilbert regularity of the corresponding homogeneous ideal and apply our methods to CHY scattering equations. This is a joint work with Viktoriia Borovik and Simon Telen.
