内容記述
The two and three-dimensional discrete Kepler motions were presented in [5, 6] which conserve all of the constants of motion including the Runge-Lenz vectors. Sequences of points described by the discrete Kepler motions exactly lie in the continuous orbits of the Kepler motions. However, the time evolution of the discrete Kepler motions is different from that of the continuous Kepler motions. In this Letter new formulas are presented which describe the time when the two and three-dimensional continuous Kepler motions arrive at the points located by the discrete Kepler motions.As an application a time adjustment of the discrete Kepler motions is performed. Consequently an accurate numerical integration algorithm for the Kepler motions is designed.
