Almost every scientist has heard of catastrophe theory and knows that there has been a considerable amount of controversy surrounding it. Yet comparatively few know anything more about it than they may have read in an article written for the general public. The aim of this book is to make it possible for anyone with a comparatively modest background in mathematics - no more than is usually included in a first year university course for students not specialising in the subject - to understand the theory well enough to follow the arguments in papers in which it is used and, if the occasion arises, to use it. Over half the book is devoted to applications, partly because it is not possible yet for the mathematician applying catastrophe theory to separate the analysis from the original problem. Most of these examples are drawn from the biological sciences, partly because they are more easily understandable and partly because they give a better illustration of the distinctive nature of catastrophe theory. This controversial and intriguing book will find applications as a text and guide to theoretical biologists, and scientists generally who wish to learn more of a novel theory.

Chaos theory challenges the presumption that the cosmos is orderly, linear, and predictable--but it does not imply pure randomness and chance events. Rather, chaos-informed postmodernist analysis introduces a new vision by celebrating unexpected, surprise, ironic, contradictory, and emergent elements. Scholars in many disciplines are taking this perspective as an alternative to the entrenched structural functionalism and empiricism rooted in linear science. In the early 1990s studies began to emerge applying chaos theory to criminology, law, and social change. This book brings together some of the key thinkers in these areas. Part I situates chaos theory as a constitutive thread in contemporary critical thought in criminology and law. It seeks to provide the reader with a sensitivity to how chaos theory fits within the postmodern perspective and an understanding of its conceptual tools. Part II comprises chapters on applying the chaos perspective to critical criminology and law and, beyond, to peacemaking. Part III presents studies in chaos-informed perspectives on new social movement theory, social change, and the development of social justice. While the book emphasizes the usefulness of the conceptual tools of chaos theory in critical criminology and law, its ultimate goal goes beyond theory-building to provide vistas for understanding the contemporary social scene and for the development of the new just society.

In this volume are collected notes of lectures delivered at the First In ternational Research Institute of the Mathematical Society of Japan. This conference, held at Tohoku University in July 1993, was devoted to geometry and global analysis. Subsequent to the conference, in answer to popular de mand from the participants, it was decided to publish the notes of the survey lectures. Written by the lecturers themselves, all experts in their respective fields, these notes are here presented in a single volume. It is hoped that they will provide a vivid account of the current research, from the introduc tory level up to and including the most recent results, and will indicate the direction to be taken by future researeh. This compilation begins with Jean-Pierre Bourguignon's notes entitled "An Introduction to Geometric Variational Problems," illustrating the gen eral framework of the field with many examples and providing the reader with a broad view of the current research. Following this, Kenji Fukaya's notes on "Geometry of Gauge Fields" are concerned with gauge theory and its applications to low-dimensional topology, without delving too deeply into technical detail. Special emphasis is placed on explaining the ideas of infi nite dimensional geometry that, in the literature, are often hidden behind rigorous formulations or technical arguments."

From its original meaning as a gaping void, or the emptiness that precedes the whole of creation, chaos has taken on the exclusive meaning of confusion, pandemonium and mayhem. This definition has become the overarching word to describe any challenge to the established order; be it railway strikes or political dissent, any unexpected event is routinely described in the media and popular parlance as 'chaos'. In his incisive new study, Stuart Walton argues that this is a pitifully one-dimensional view of the world, as he looks to many of the great social, political, artistic and philosophical advances that have emerged from periods of disorder and from the refusal to think within the standard paradigms. Exploring this worldview, Walton contends that we are superstitious about states of affairs in which anything could happen because we have been taught to prefer the imposition of rules in every aspect of our lives, from our diets to our romances. Indeed, in An Excursion through Chaos he demonstrates how it is these very restrictions that are responsible for the alienation that has characterised postwar society, a state of disengagement that could have been avoided if we had taken a less fearful attitude towards the unravelling of order.

This book provides a complete understanding of chaotic dynamics in mathematics, physics, and the real world, with an explanation of why it is important and how it differs from the idea of randomness. The author draws on certain physical systems and phenomena, for example the weather forecast, a pendulumn, a coin toss, mass transit, politics, and the role of chaos in in gambling and the stock-market.

Mathematical symmetry and chaos come together to form striking, beautiful colour images throughout this impressive work, which addresses how the dynamics of complexity can produce familiar universal patterns. The book, a richly illustrated blend of mathematics and art, was widely hailed in publications as diverse as the New York Review of Books, Scientific American, and Science when first published in 1992. This much-anticipated second edition features many new illustrations and addresses the progress made in the mathematics and science underlying symmetric chaos in recent years; for example, the classifications of attractor symmetries and methods for determining the symmetries of higher dimensional analogues of images in the book. In particular, the concept of patterns on average and their occurrence in the Faraday fluid dynamics experiment is described in a revised introductory chapter. The ideas addressed in this book have been featured at various conferences on intersections between art and mathematics, including the annual Bridges conference, and in lectures to art students at the University of Houston.

Komplexe dynamische Systeme werden in verschiedenen Wissenschaftsdisziplinen untersucht - von Physik, Chemie, Biologie und Medizin uber Kognitionswissenschaften und Psychologie bis zu Soziologie und OEkonomie. Dieser Band zieht Bilanz und zeigt kunftige Forschungsperspektiven auf. Gemeinsames methodisches Thema ist die Modellierung komplexer Systeme, deren Dynamik durch Nichtlinearitat bestimmt ist. Mathematische Methoden und Computersimulationen machen aber nur Sinn, wenn sie mit konkreten einzelwissenschaftlichen Analysen verbunden sind. Das Buch liefert nicht nur fachubergreifende Informationen uber den aktuellen Forschungsstand, sondern kann auch von Nichtspezialisten als Einfuhrung in das spannende Gebiet komplexer Systeme und nichtlinearer Dynamik in Natur und Gesellschaft gelesen werden.

The phenomena of oscillations, travelling waves, and chaos in reacting chemical systems began as curiosities but now support an active, international research field. This book shows how these "exotic" patterns arise from the underlying chemical mechanisms. The origin of "chemical feedback" is revealed using three example reactions: the isolate-reductant (Landolt) reaction, the Belousov-Zhabotinsky reaction, and the combustion of hydrogen. Thermal feedback is also discussed. These mechanisms lead to clock reactions and travelling reaction fronts, thermal runaway, and flames; to oscillations and excitability; to target patterns, spiral and scroll waves; to bistability, ignition, extinction, and hysteresis; and to complex oscillations and chaos in flow reactors. These phenomena are related to important processes in biology, including the development of cardiac arrhythmias, nerve signal transmission, and animal coat patterning.

In a totally new way of looking at financial economics, Nonlinear Pricing abandons the traditional assumptions of equilibrium in economics and randomness in a time-series. These shortcomings are becoming increasingly awkward given a superior technological infrastructure and advances in mathematics and the sciences. Despite these advances and their empirical proof, much remains confused or muddled. In this groundbreaking new book, leading hedge fund manager Christopher T. May explores the nature and role of nonlinearity, an inherent part of everyday reality, and illustrates a profit-making strategy.

One of the many striking applications of nonlinear technology in recent years, nonlinear pricing uses cutting-edge technology to identify and exploit patterns hidden within the seemingly helter-skelter rise and fall of daily stock prices. Nonlinear Pricing sheds much needed light on the principles behind this innovative view of reality and provides clear explanations of how it is employed to predict—at least partially—the unpredictable.

Beginning with an incisive introduction to the topic, May presents the roots of nonlinearity through the examples of calendrics, geometry, and music. He then illustrates the application and integration of various nonlinear technologies, including genetic algorithms, fuzzy logic, fractal imaging, and nonlinear dynamics, to such essentials as trading strategies, asset allocation, risk management, and derivative pricing and hedging. Along with practical methodologies and a wealth of real-world examples, this comprehensive resource contains a glossary of terms, a bibliography, and in-depth information on:

• Fractal analysis—power law distributions, fractional Brownian motion, and their relationships
• The Hurst Exponent—the KAOS screen and its practical implementation
• Resonance—time domain versus frequency domain, Brownian motion, and the Gaussian distribution
• Advanced concepts—Soros's Reflexivity, nonequilibrium economics, kernel of theoretical nonlinear pricing, May's Law, resolution and resonance.

"Nonlinear Pricing is an eminently readable book which I found satisfied both the theorist and the practitioner in me. For the theorist, there are new insights into the relationship between complexity and the markets. For the practitioner, there are practical ideas on how to fashion investment strategies. I highly recommend Nonlinear Pricing to all students of the markets."—Edgar E. Peters, Chief Investment Strategist, PanAgora Asset Management; author, Chaos and Order in the Capital Markets.

"Nonlinear Pricing goes further than any book I am aware of in drawing a connection between the real world of economics and the new ideas about economics coming from the science of self-organized systems. Written in a lively, informal style, this is a wonderful read for those of us who have been wondering whether anyone understands anything at all about how markets work."—Lee Smolin, PhD, Department of Physics, Pennsylvania State University.

"Required reading for the enlightened financial professional. Enjoyable for the intelligent investor. A dash of physics, bite-sized pieces of nonlinear concepts, and a broth of hands-on experience make this a cookbook for the modern trader."—Richard E. Morley, Potts Medal recipient and founder of the Breakfast Club.

"A real eye-opener—Nonlinear Pricing explains a complex subject in easy terms and makes the reader aware of the many opportunities offered by this new technology."—Richard Olsen, founder, Olsen and Associates, Zurich.

"I, of course, think highly of this book as it credits Dance of the Money Bees with inventing 'swarm theory,' now a discipline in computer science. There are many other splendid insights."—John Train, author and President of the Montrose Fund

"An extraordinary tour d'horizon, this book challenges conventional thinking about finance, investing, and much else besides. Brimming with ideas and eye-opening connections, it makes a powerful case for our need to understand the extent to which nonlinearity shapes our lives."—Andrew Freeman, Managing Editor, Financial Services, The Economist Intelligence Unit; coauthor, Seeing Tomorrow: Rewriting the Rules of Risk.

"Nonlinear Pricing: Theory & Applications by Christopher T. May makes nice reading even for people like me who are not economists. This is an ambitious book as it presents economics starting from fundamental physics. It deserves a large readership."—Ilya Prigogine, 1977 Nobel Laureate, Chemistry; author, The End of Certainty; and world's foremost non-equilibrium scientist.

Written by one of the few practitioners using this breakthrough methodology to trade the markets successfully, Nonlinear Pricing fills an important niche in investment literature. It is a must read for anyone seeking to understand—and capitalize on—twenty-first century financial economics.

Das Buch wendet sich an Leser, die - uber die rein computergraphische Darstellung hinaus - an einer analytischen Untersuchung von chaotischen und nichtchaotischen Differenzen- und Differentialgleichungssystemen interessiert sind. Breiter Raum wird der Durchrechnung von Beispielen gegeben. Dargestellt werden zunachst qualitative Methoden als auch solche, die das Auffinden von Attraktoren, Bifurkationen etc. und deren Klassifikation in Abhangigkeit von den Systemparametern gestatten. Der letzte Teil schliesslich widmet sich der quantitativen Beschreibung chaotischer Systeme. Dazu werden zuerst die Begriffe Chaos und Fraktal exakt definiert und dann die verschiedenen fraktalen Dimensionen, Lyapunov-Exponenten, Entropien etc. eingefuhrt und durch Beispiele begrundet."

What is life? Is it just the biologically familiar--birds, trees, snails, people--or is it an infinitely complex set of patterns that a computer could simulate? What role does intelligence play in separating the organic from the inorganic, the living from the inert? Does life evolve along a predestined path, or does it suddenly emerge from what appeared lifeless and programmatic?

In this easily accessible and wide-ranging survey, Claus Emmeche outlines many of the challenges and controversies involved in the dynamic and curious science of artificial life. Emmeche describes the work being done by an international network of biologists, computer scientists, and physicists who are using computers to study life as it could be, or as it might evolve under conditions different from those on earth.

Many artificial-life researchers believe that they can create new life in the computer by simulating the processes observed in traditional, biological life-forms. The flight of a flock of birds, for example, can be reproduced faithfully and in all its complexity by a relatively simple computer program that is designed to generate electronic "boids." Are these "boids" then alive? The central problem, Emmeche notes, lies in defining the salient differences between biological life and computer simulations of its processes. And yet, if we can breathe life into a computer, what might this mean for our other assumptions about what it means to be alive?

"The Garden in the Machine" touches on every aspect of this complex and rapidly developing discipline, including its connections to artificial intelligence, chaos theory, computational theory, and studies of emergence. Drawing on the most current work in the field, this book is a major overview of artificial life. Professionals and nonscientists alike will find it an invaluable guide to concepts and technologies that may forever change our definition of life.
