报告摘要:In the classical Kepler problem with center of attraction O, Lamberts 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.
