Local normal forms for geodesically equivalent pseudo-Riemannian metrics
Abstract
Two pseudo-Riemannian metrics g and g are geodesically equivalent, if they share the same (unparameterized) geodesics. We give a complete local description of such metrics which solves the natural generalisation of Beltrami problem for pseudo-Riemannian metrics.
