Query: Geometric Recursion from Polytope Triangulations and Twisted Homology   A geometric approach to understanding recursion relations for scattering
amplitudes is developed. We achieve this by studying intersection numbers of
triangulated accordiohedra presented as hyperplane arrangements. The
cancellation of spurious divergences is subsequently realized as a topological
no-boundary condition.
