Homoclinic orbits of positive definite Lagrangian systems

If the Aubry set satisfies some topological hypothesis, such as , then the α-function has a flat. In this paper, we will prove that has infinitely many -minimal homoclinic orbits when c′ is on the boundary of the maximal flat of the α-function. These homoclinic orbits are different from the usually called multi-bump solutions.
