This paper considers positive definite time-periodic Hamiltonian systems. The author reviews the conditions on equilibria (i.e., local maxima of the potential energy) which guarantee the existence of homoclinic trajectories. He then uses variational methods to establish that similar conditions on Mather sets also guarantee the existence of homoclinic orbits.
