Dynamics and mission design near libration points, advanced methods for collinear points
Gómez, Gerard; Jorba, Angel; Masdemont Soler, Josep; Simó Torres, Carlos (2000)
Article
Accés obertPreface and table of contents of a forthcoming book published by World Scientific -
Dynamics and mission design near libration points, advanced methods for triangular points
Gómez, Gerard; Jorba, Angel; Masdemont Soler, Josep; Simó Torres, Carlos (2000)
Article
Accés obertThe final objective of this work is to understand, analyze and compute the kinds of motion that appear on a vicinity (may be a large vicinity) of the geometrically defined equilateral points of the Earth-Moon system, as a ... -
Effective stability for periodically perturbed hamiltonian systems
Jorba, Angel; Simó Torres, Carlos (1994)
Article
Accés obertIn this work we present a method to bound the diffusion near an elliptic equilibrium point of a periodically time-dependent Hamiltonian system. The method is based on the computation of the normal form (up to a certain ... -
On quasiperiodic perturbations of elliptic equilibrium points
Jorba, Angel; Simó Torres, Carlos (1995)
Article
Accés obertThis work focusses on quasiperiodic time-dependent perturbations of ordinary differential equations near elliptic equilibrium points. This means studying $$ \dot{x}=(A+\varepsilon Q(t,\varepsilon))x+\varepsilon ... -
Resonance tongues and spectral gaps in quasi-periodic schrödinger operators with one or more frequencies. A numerical exploration
Puig Sadurní, Joaquim; Simó Torres, Carlos (2010-07)
Report de recerca
Accés obertAbstract. In this paper we investigate numerically the spectrum of some representative examples of discrete one-dimensional Schr¨odinger operators with quasi-periodic potential in terms of a perturbative constant b and ... -
Resonance tongues in the quasi-periodic hill-Schrödinger equation with three frequencies
Puig Sadurní, Joaquim; Simó Torres, Carlos (2010-07)
Report de recerca
Accés obertIn this paper we investigate numerically the following Hill’s equation x00 + (a + bq(t))x = 0 where q(t) = cos t + cosp2t + cosp3t is a quasiperiodic forcing with three rationally independent frequencies. It appears,also, as ... -
