Informationen zum Autor Annick Lesne is a Researcher at the Institut des Hautes Etudes Scientifiques. Her research lies in renormalization methods for dynamical systems, non equilibrium statistical physics, and applications of dynamical systems theory and statistical mechanics to biological systems. Klappentext Originally conceived some thirty years ago in the context of quantum electrodynamics, renormalization methods have progressively developed into an indispensable analytical tool used in widely varying domains of physics and applied mathematics, such as phase transitions and critical phenomena dynamical systems and chaos developed turbulence fractal structures and complex systems percolation polymer physics diffusion in disordered media measure theory and stochastic processes. By explaining the fundamental principles of renormalization theory ? such as scale invariance and universality ? which lie behind all the technical variations, this book aims to guide the reader to a more unified understanding of today's physics. The book is based on a very accessible main text, supplemented by several more specialized sections; it is intended for graduate students and for researchers who are seeking an introduction to a new area of electrodynamics or a general overview of the physical phenomena to which renormalization methods are applied. Zusammenfassung Renormalization analysis reveals how microscopic mechanisms can organize themselves to produce macroscopic consequences. These techniques are applied in various fields of physics! from phase transitions and magnetic systems! to dynamical systems! percolation and fractal structures! random walks! and polymers.
