Compartmentalized Reaction Diffusion Systems
Raymond Kapral (University of Toronto)

The spatial and temporal dynamics of compartmentalized reaction-diffusion systems consisting of a collection of reactive domains separated by chemically inactive regions will be discussed. The reactive dynamics is governed by multi-step reaction mechanisms and each reactive domain is specific to a particular elementary step or collection of elementary steps of the global reaction mechanism. Far-from-equilibrium situations where the global kinetics can give rise to complex states such as bistability, oscillations or chaos will be discussed. The effects of compartmentalization will be illustrated by a study of the influence of diffusion, reactive domain size and domain distribution on the nature of the spatio-temporal dynamics. Since compartmentalization is the rule in biology and may occur in the laboratory, this study provides some insight into the phenomena that might be seen in such circumstances.
