review text: Verf. untersucht in kovarianter Weise, ob eine Änderung der Signatur der Metrik an einer Hyperfläche eines Robertson-Walker-Universums möglich ist, und zeigt, daß die Einsteinschen Feldgleichungen mit Skalarfeld bzw. barotroper Flüssigkeit als Quelle einen solchen Sprung zulassen. Für das Skalarfeld wird diskutiert, wann eine Signaturänderung auftreten sollte, und einige Beispiele dafür werden angegeben.
