Lower bounds for homoclinic splitting. Some examples. II.

Abstract : In a three time scales model, coming from a problem of celestial mechanics, a lower bound for the homoclinic splitting is found,by exploiting suitable cancellations. From such bound the existence of heteroclinic chains can be proved.
