Description of Research

The Sonderforschungsbereich (Sfb) 555 is a cooperation between seven universities and research institutes in Berlin and Potsdam. Financed by the Deutsche Forschungsgemeinschaft (DFG), it started its work in 1998. In our project (C3), we investigate synchronization properties of systems with time delay. Our current research follows these directions:
  1. Delay effects in noisy systems
  2. Controlling synchronization with time delay
  3. Finding time delay from data
