Arnold diffusion for an a priori unstable Hamiltonian system with 3 + 1/2 degrees of freedom
{{output}}
In the present paper, we apply the geometrical mechanism of diffusion in an a priori unstable Hamiltonian system [L. Chierchia and G. Gallavotti, Ann. l'I.H.P. Phys. théor. 60, 1-144 (1994)] with 3 + 1/2 degrees of freedom. This mechanism consists of combinin... ...
