Evolution of Dynamical Structures in Complex Systems

"Evolution of Dynamical Structures in Complex Systems" is dedicated to the founder of synergetics, Hermann Haken, on the occasion of his 65th birthday. This volume is an attempt to gather together and review the new results and de velopments achieved by researchers from various fields during the last few years. The contents bear witness to the great success in the development of general approaches to synergetic systems as well as remarkable progress in the more tra ditional fields of synergetics such as lasers and nonlinear optics, hydrodynamics, condensed matter physics, biology, and sociology. Since their inception, the concepts of synergetics and rigorous mathematical theories have been extended to other scientific disciplines such as medicine, artifi cial intelligence and synergetic computers, and psychology. Here too, these ideas have yielded new insights, raised unexpected questions and produced innovations in both theoretical and experimental projects. The conception of self-organization, the central theme of Hermann Haken' s scientific work, has stimulated epistemo logical studies that draw relations between synergetics and the German romantic "Naturphilosophie". It is fascinating to observe how these intuitive notions of self-organization, etc., have now evolved into a precise and holistic scientific comprehension of synergetic systems. We express our deep gratitude to Dr. Angela Lahee from Springer-Verlag for her valuable help during the preparation of this book. Stuttgart R. Frjedrjch March 1992 .4..

Autorentext
Rudolf Friedrich (Jg. 1922) ist als Diplom-Bergingenieur fachlich ausgewiesen. Der vielseitige Autor und Herausgeber hat sich nicht nur mit Industriegeschichte auseinandergesetzt. Einen Namen gemacht hat sich Rudolf Friedrich vor allem in der keltisch-fränkischen Sprach- und Migrationsforschung.
