Abstract

We consider the second order Hamiltonian system:

where () and () is a potential with a singularity, i.e., as . We prove the existence of a homoclinic orbit of (HS) under suitable assumptions. Our main assumptions are the strong force condition of Gordon [8] and the uniqueness of a global maximum of .

Résumé

On considère le système hamiltonien du second ordre

() et est un potentiel singulier : quand . On montre alors l’existence d’une orbite homocline, sous l’hypothèse dite de « strong farce » (Gordon [8]) et à condition que le maximum de soit unique.
