-like invariants of periodic orbits of the second kind in the restricted three body problem
arXiv:1708.08392
Abstract
We determine three invariants: Arnold's -invariant as well as and invariants, which were introduced by Cieliebak-Frauenfelder-van Koert, of periodic orbits of the second kind near the heavier primary in the restricted three-body problem, provided that the mass ratio is sufficiently small.
