Synchronization of a hierarchical ensemble of coupled excitable oscillators — •Cornelia Petrovic and Rudolf Friedrich — Institut für Theoretische Physik, Westfälische Wilhelms-Universität Münster

In our work we investigate a model for an ensemble of globally coupled excitable oscillators. These oscillators are relaxation oscillators with hierarchically ordered frequencies and show several kinds of synchronization phenomena - from partial up to global synchronization - which can be detected in selfaffine features in the temporal evolution of the system. In our contribution we shall present some details of analytical and numerical analysis of the given system.

Our model was motivated by an experiment concerning the exothermic CO-oxidation on palladium supported catalyst (C.Ballandis, P.J.Plath, Journal of Non-Equilibrium Thermodynamics 25 3/4, 301 (2000)).
