Homoclinic orbits for a class of singular second order Hamiltonian systems in ℝ3

We consider a conservative second order Hamiltonian system q ¨ + V ( q ) = 0 in ℝ3 with a potential V having a global maximum at the origin and a line l ∩ 0 = ϑ as a set of singular points. Under a certain compactness condition on V at infinity and a strong force condition at singular points we study, by the use of variational methods and geometrical arguments, the existence of homoclinic solutions of the system.
