Variational property of periodic Kepler orbits in constant curvature spaces
We study the variational property of the periodic Kepler orbits on the sphere, the plane and the hyperbolic plane. We first classify the orbits by the two constants of motion: the energy and the angular momentum. Then, we characterize the local variational property of the closed orbits by computing...

Summary: | We study the variational property of the periodic Kepler orbits on the sphere, the plane and the hyperbolic plane. We first classify the orbits by the two constants of motion: the energy and the angular momentum. Then, we characterize the local variational property of the closed orbits by computing the Maslov-type indices. Finally, we study the global variational property of the closed orbits. We prove that the closed orbits on the hyperbolic plane minimizes the action among all loops which encircle the attracting center. |
