A note on the existence of multiple homoclinic orbits for a perturbed radial potential
From the Introduction: ``We study the existence of multiple homoclinic orbits for an autonomous second order Hamiltonian system. Recently, the existence of homoclinic orbits has been deeply investigated via variational methods. The purpose of this paper is to consider small perturbations of radial potentials and to prove the existence of at least two geometrically distinct homoclinic orbits satisfying natural initial conditions''.
