Abstract:

Travelling wave solution in a one dimensional array of two degre of freedom Hamiltonian system is considered. We show that in the long wave limit, the problem can be reduced to the analysis of the honoclinic orbits of perturbed system. with a resonance in the unperturbed system, we show that the perturbed system have multi pulse honoclinic orbits asgmptotic to a periodic orbit, or fixed points using energy phase method.Therefore,the array have travelling wave solutions analogous to multi pulse solitons.

Key words:  array, energyphasemethod, multipulsehomoclinic, soliton.
