Slow Relaxation and Phase Space Properties of a Conservative System with Many Degrees of Freedom
, 1994 We study the one-dimensional discrete $\Phi^4$ model. We compare two equilibrium properties by use of molecular dynamics simulations: the Lyapunov spectrum and the time dependence of local correlation functions.

Periodic orbits close to elliptic tori and applications to the three-body problem
, 2003 We prove, under suitable non-resonance and non-degeneracy ``twist'' conditions, a Birkhoff-Lewis type result showing the existence of infinitely many periodic solutions, with larger and larger minimal period, accumulating onto elliptic invariant tori (of
