For the first time in a single book Non-Linear Instabilities in Plasmas and Hydrodynamics presents the underlying physics of fast secondary instabilities. This exceptionally well-written introductory book discusses the basic ideas of the physics of secondary or induced nonlinear instabilities in wave-sustaining media. The authors world-renowned experts in the field have brought together the results of papers scattered throughout the literature to explain subjects as diverse as fluctuation chaos wave-turbulent instabilities vortex dynamos beam-plasma interactions plasma confinement and the origins of typhoons in the Earth's atmosphere and magnetic fields in galaxies. Paving the way for new and exciting research in the future this broad interdisciplinary book enables a wide range of physicists to apply the concepts discussed to obtain new results in plasma physics space physics hydrodynamics and geophysics.
