Effective stability for a Hamiltonian system near an elliptic equilibrium point, with an application to the restricted three body problem

- A. Giorgilli, A. Delshams, E. Fontich, L. Galgani, C. Simó
- Mathematics
- 1989

Abstract We consider an n -degrees of freedom Hamiltonian system near an elliptic equilibrium point. The system is put in normal form (up to an arbitrary order and with respect to some resonance… Expand

- Mathematics
- 15 November 1992

Abstract We report on some analytical and numerical results on the exchanges of energy in systems of the Fermi-Pasta-Ulam type, in the light of Nekhoroshev's theorem, with particular attention to the… Expand

Zero-point energy in classical non-linear mechanics☆

- C. Cercignani, L. Galgani, A. Scotti
- Physics
- 13 March 1972

Abstract It is pointed out that the critical energy for stochasticity observed in classical systems, for physical values of the parameters in the problem, is of the order of magnitude of the quantum… Expand

Some rigorous results on the Pauli-Fierz model of classical electrodynamics

- D. Bambusi, L. Galgani
- Mathematics
- 1993

We consider the dynamical system describing the classical electromagnetic field interacting with an extended rigid charged particle in the non-relativistic approximation (the Pauli-Fierz model);… Expand

- Physics, Medicine
- Physical review letters
- 10 January 2003

We consider the Landau-Teller model, which is a prototype for the exchanges of energy, in molecular collisions, between internal degrees of freedom and those of the center of mass. We show that the… Expand

Numerical computations on a stochastic parameter related to the Kolmogorov entropy

- M. Casartelli, E. Diana, L. Galgani, A. Scotti
- Physics
- 1 May 1976

A stochastic parameter which appears to be related to the Kolmogorov entropy is computed for a system of $N$ particles in a line with the nearest-neighbor Lennard-Jones interaction. It is found that… Expand
