The Keplerian and mean motions : a geometrical study / Y. Maeyama.
Abstract:
'The point of reference to which the mean motion of the planets against Keplerian motion can optimally be applied and the behavior of its astronomical functions are analysed mathematically. To the results of our problem, which was solved by the first and second laws of Kepler, virtually all models of planetary motions seem to be related.' From the summary
