viii blems as the study of catalytic chemical reactions in the laboratory scale, quantum optics, hydrodynamic instabilities, or large scale phenomena of interest in physics, geology, atmospheric dynamics and climatology. We expect that the present Volume will acquaint researchers and advanced students in geosciences with the concepts and tools of dyna- mical systems and will thus serve as a jumping off point for new developments and new points of view.
