Reaction-Diffusion Systems Arising in Chemistry

Many physical, chemical, biological, environmental and even sociological processes are driven by reaction-diffusion systems. These aremulti-component models involv- ing two different mechanisms: on the one hand there is diffusion, a random particle movement, and on the other hand there are chemical, biological or sociological re- actions representing instantaneous interactions, which depend on the state variables themselves and possibly also explicitly on the particles’ position.
