Abstract
The method of Melnikov is generalized to non-autonomous maps. If the Melnikov function has infinitely many zeros with derivatives bounded away from zero then the system admits a generalized hyperbolic set as it was introduced in part I. The developed theory is applied to almost periodically perturbed differential equations.
Zusammenfassung
Die Methode von Melnikov wird verallgemeinert für nichtautonome Abbildungen. Falls die Melnikov-Funktion unendlich viele Nullstellen mit von Null weg beschränkten Ableitungen hat, dann enthält das System eine verallgemeinerte hyberbolische Menge, wie sie in Teil I eingeführt wurde. Die entwickelte Theorie wird auf fast periodisch gestörte Systeme angewandt.
