Twistor Theory of Dancing Paths
Given a path geometry on a surface U, we construct a causal structure on a four-manifold which is the configuration space of non-incident pairs (point, path) on U. This causal structure corresponds to a conformal structure if and only if U is a real projective plane, and the paths are lines. We give...
