摘要
We show existence of infinitely many homoclinic orbits at the origin for a class of singular second-order Hamiltonian systems ii + V-u(t,u) = 0, -infinity < t < infinity. We use variational methods under the assumption that V(t, u) satisfies the so-called "Strong-Force" condition. (C) 2013 Elsevier Inc. All rights reserved.
