Time-Dependent Perturbations of Dynamical Systems (Part I of II)

Time varying perturbations of dynamical systems can exhibit a qualitative behavior that may differ considerably from the behavior of the nominal, time independent models. These differences can be seen e.g. in bifurcation scenarios, stability behavior, spectral properties, global analysis, and chaotic and other complex limit behavior. The talks in this minisymposium will address perturbed dynamical systems from these points of view and will present an overview over the added complexity in the presence of time varying perturbations, in applications from mathematical biology to physics to control theory.
