Synchronization of a hierarchical ensemble of coupled excitable oscillators — •Cornelia Petrovic and Rudolf Friedrich — Institut für Theoretische Physik, Westfälische Wilhelms-Universität, Wilhelm-Klemm-Str. 9, D-48149 Münster

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)) we investigate a model for an ensemble of globally coupled nonlinear oscillators. These oscillators are relaxation oscillators with different frequencies showing various kinds of synchronization phenomena (from partial up to global synchronization). We focus on the emergence of selfaffine features in the temporal evolution of the system. In our contribution we shall present a detailed mathematical analysis of this system.
