    Die behandelte Aufgabe besteht darin, zu der Differentialgleichung \[ \frac{d^2y}{dx^2}+X_1y\;=\;\psi_0+\psi_2y^2+\psi_3y^3+\ldots \] unter gewissen Voraussetzungen über die Form und die Grössenordnung von \(y\) und den Coefficienten \(X_1, \psi\) eine nur aus periodischen Gliedern bestehende Lösung durch successive Approximation zu finden. Der Nerv des Verfahrens, welches an dem Beispiel \[ \frac{d^2y}{dx^2}+\alpha\cos{}\lambda x.y\;=\;\psi_0+\ldots \] (\(\alpha\) und \(\lambda\) konstant) erläutert wird, besteht in einer passenden Spaltung des Coefficienten \(X_1\), um die auftretenden nichtperiodischen Glieder zu beseitigen.
