Fecha de publicación: | 27-abr-2021 | Editor: | Elsevier | Citación: | Communications in Nonlinear Science and Numerical Simulation 101: 105859 (2021) | Resumen: | The goal of this paper is to present a methodology for the computation of invariant tori in Hamiltonian systems combining flow map methods, parameterization methods, and symplectic geometry. While flow map methods reduce the dimension of the tori to be computed by one (avoiding Poincaré maps), parameterization methods reduce the cost of a single step of the derived Newton-like method to be proportional to the cost of a FFT. Symplectic properties lead to some magic cancellations that make the methods work. The multiple shooting version of the methods are applied to the computation of invariant tori and their invariant bundles around librational equilibrium points of the Restricted Three Body Problem. The invariant bundles are the first order approximations of the corresponding invariant manifolds, commonly known as the whiskers, which are very important in the dynamical organization and have important applications in space mission design. | Versión del editor: | http://doi.org/10.1016/j.cnsns.2021.105859 | URI: | http://hdl.handle.net/10261/256671 | DOI: | 10.1016/j.cnsns.2021.105859 | Identificadores: | doi: 10.1016/j.cnsns.2021.105859 issn: 1007-5704 |
