Abstract

Consideration is given to the homoclinic solutions of ordinary differential equations. We first review the Melnikov analysis to obtain Melnikov function, when the perturbation parameter is zero and when the differential equation has a hyperbolic equilibrium. Since Melnikov analysis fails, using Homotopy Analysis Method (HAM, see [Liao SJ. Beyond perturbation: introduction to file homotopy analysis method.

Then we show that the Melnikov type function call be obtained as it special case of this homotopy analysis method. Finally, homoclinic solutions arc obtained (for nontrivial examples) analytically by HAM, and arc presented through graphs. (C) 2009 Published by Elsevier Ltd.
