Abstract
We prove the existence of infinitely many homoclinic solutions for a class of second order hamiltonian systems of the form where is superquadratic and , as . In fact we prove that such a kind of systems admit a “multibump” dynamics.
Résumé
On montre l’existence d’une infinité de solutions homoclines d’une classe de systèmes hamiltoniens du second ordre de la forme où est superquadratique et , quand . On montre en particulier que cette famille des systèmes admet une dynamique “multi-bosses”.
