| Abstract: | We study a model which is a periodic lattice system with nearest neighbors coupling. Using the variational methods, we show the existence of diffusion orbits under a generic perturbation of time periodic. |
| Keywords: | Hamiltonian system lattice system Aubry-Mather theory variational methods |
