Contains a treatment of the kepler problem, i.e. the two body problem. First the properties of the problem are demonstrated. In the second part a unifying point of view is presented which centers the exposition on the intrinsic group-geometrical aspects. The third part gives a geometrical description of the perturbation theory of the Kepler problem. «
