Self-Organization: Autowaves and Structures Far from Equilibrium

According to its definition, Synergetics is concerned with systems that produce macroscopic spatial, temporal, or functional structures. Autowaves are-a specific, yet very important, case of spatio-temporal structures. The term "autowave" was coined in the Soviet Union in analogy to the term "auto-oscillator". This is - perhaps too literal - translation of the Russian word "avto-ostsillyatory" (= self- oscillator) which in its proper translation means "self-sustained oscillator". These are oscillators, e. g., clocks, whose internal energy dissipation is compensa- ted by a (more or less) continuous power input. Simi larly, the term "autowaves" de- notes propagation effects - including waves - in active media, which provide spa- tially distributed energy sources and thus may compensate dissipation. An example which is now famous is represented by spiral or concentric waves in a chemically active medium, undergoing the Belousov-Zhabotinsky reaction. This book provides the reader with numerous further examples from physics, chem- istry, and biology - e. g., autowaves of the heart. While the Belousov-Zhabotinsky reaction is now widely known, a number of very important results obtained in the Soviet Union are perhaps less well known. I am particularly glad that this book may help to make readers outside the Soviet Union acquainted with these important exper- imental and theoretical findings which are presented in a way which elucidates the common principles underlying this kind of propagation effects.
