| Abstract |
The restricted problem of three bodies (material points) is considered. The orbits of the
main attracting bodies are assumed to be ellipses of small eccentricity, and the passively gravitating
body during its motion can leave the plane of the orbits of the main bodies (spatial problem). The stability of body motion corresponding to triangular Lagrangian libration points is investigated. A characteristic feature of the spatial problem under study is the presence of resonance due to the equality of
the Keplerian motion period of the main bodies and the linear oscillation period of the passively gravitating body in the direction perpendicular to the plane of their orbits. Using the methods of classical
perturbation theory, Kolmogorov—Arnold—Moser (KAM) theory and computer algebra algorithms,
the nonlinear problem of stability for most (in the Lebesgue-measure sense) initial conditions and formal stability (stability in any arbitrarily high finite approximation with respect to the coordinates and
impulses of perturbed motion) are investigated. |
