Im Oberseminar "Angewandte Analysis" werden vertiefende Fragestellungen aus dem Bereich der nichtlinearen Analysis behandelt, meist mit inhaltlicher Fokussierung auf partielle Differentialgleichungen. In flexiblem Wechsel zwischen (Impuls-)Vortrag und Diskussion werden aktuelle Forschungsergebnisse vorgestellt und Lösungsansätze für offene Probleme diskutiert.
