Zusammenfassung
Nichtlineare Prozesse sind in Natur, Technik und Gesellschaft weit verbreitet. Bei der Untersuchung dieser Phänomene gibt es heute schon große Fortschritte, die sich aber hauptsächlich auf Systeme mit wenigen Freiheitsgraden (niedrig-dimensionale Systeme) beziehen. Reale komplexe Systeme sind allerdings im allgemeinen hochdimensional; typische Beispiele dafür finden sich in den Erd-und Umweltwissenschaften oder der Astrophysik. Schwerpunkt sind dabei Fragestellungen zu kritischen Phänomenen, z.B. Klima-relevante Variationen der Sonnenaktivität oder die Vorhersagbarkeit starker Erdbeben. Diese natürlichen Systeme, die meist fernab vom thermodynamischen Gleichgewicht sind, zeichnen sich durch vielfältige komplexe Rückkopplungen und reichhaltige Dynamik in einem breitbandigen Spektrum raumzeitlichen Verhaltens aus; sie sind eine besondere Herausforderung für die Nichtlineare Dynamik.
