Arnold diffusion: an overview through dynamical astronomy
(Elsevier, 2002-12)
The aim of this work is to review the fundamental ideas behind the stability problem, emphasizing the differences between two well-known mechanisms that could lead to chaos, namely overlap of resonances and Arnold diffusion. ...
The construction of a Poisson structure out of a symmetry and a conservation law of a dynamical system
(1996)
A method to construct Hamiltonian theories for systems of both ordinary and partial differential equations is presented. The knowledge of a Lagrangian is not at all necessary to achieve the result. The only ingredients ...
Inner satellites of Neptune: I the disturbing function
(Elsevier B.V., 2005-01-01)
In this work, we focus our attention to the expansion of the disturbing function (R) which governs the dynamics of a satellite (natural or artificial) in the Neptune-Triton system. What makes this problem quite unusual, ...
