A novel solution to Kepler s problem

European Journal of Physics, 2003
Summary: The standard (unperturbed) Kepler problem is expressed in Kustaanheimo-Stiefel form and solved utilizing the algebra of quaternions. This provides the necessary background to understand some of the new techniques of celestial mechanics.

On a first integral of the Kepler problem

Journal of Mathematical Physics, 1997
A quadratic first integral of the Kepler problem, obtained by Benenti (“Orthogonal separable dynamical systems,” 5th International Conference on Differential Geometry and its Applications, 24–28 August 1992, Silesian University at Opava) through separation in elliptic coordinates, is shown to be intimately connected with the pre-quantization of the ...

Quantization of the Kepler Problem

2003
The expression “quantization of a mechanical system” is somewhat vague and this is not the place to give an exact and precise definition (which, probably’, can not be given at all). So we take it for granted that the reader is familiar with the fascinating subtleties of quantum mechanics and only recall that, from the physical point of view, quantizing

Perturbations of the Kepler Problem

2003
In this chapter we study the perturbations of the Kepler problem, i.e., the motion of a particle with mass m and Hamiltonian $$H(\vec{Q},\vec{P}) = \frac{1}{{2m}}{{P}^{2}} - \frac{k}{Q} + \varepsilon {{H}_{p}}(\vec{Q},\vec{P}),$$ where \({{H}_{p}}(\vec{Q},\vec{P})\) the perturbation Hamiltonian and E a dimension-less, “small” parameter.
