Research output: Contribution to journalArticlepeer-review


In this paper, we present an explicit integral formula for the high order Melnikov function D1(t0) for periodically perturbed pendulum equations. The acquired integral formula is then applied to a specific pendulum equation to offer an example of high frequency perturbation, of which the classical Melnikov function D0(t0) fails to dominate the higher order term εD1(t0).
