报告摘要:In the classical Kepler problem with center of attraction O, Lambert’s theorem states that the passing time from point A to point B along a Keplerian arc with energy H does not vary along all deformations which keep fix H, the distance ‖AB‖, and the sum of distances ‖OA‖+‖OB‖. In this talk, we shall discuss this as well as an analogous phenomenon in the spherical Kepler problem.
This is a joint work with Alain Albouy from Paris Observatory.
