Wavelets in Physics: A Comprehensive Survey of Wavelet Transform Applications in Physical Sciences by J. C. Van Den Berg

Introduction

Wavelets have emerged as one of the most powerful mathematical tools for analyzing complex signals and phenomena across the sciences. In Wavelets in Physics, edited by J. C. Van Den Berg, a distinguished group of contributors presents a comprehensive survey of how wavelet transforms are applied to a wide array of physical problems. This hardcover volume from Cambridge University Press is an essential reference for graduate students, researchers, and professionals in physics, applied mathematics, and engineering who wish to understand and harness the power of wavelet analysis in their work.

Book Overview

This book provides a thorough introduction to the theory and practice of wavelet transforms, focusing on their utility in physics. Unlike the classical Fourier transform, which gives only global frequency information, the wavelet transform allows for local, scale-dependent analysis of signals and images. The text covers both the continuous wavelet transform (CWT) for detailed analysis and the discrete wavelet transform (DWT) for efficient data compression, transmission, and numerical computation. Each chapter is written by an expert in the field, ensuring depth and accuracy, while the editor has woven the contributions into a coherent narrative suitable for readers with a basic background in mathematics and physics.

Key Highlights

• Comprehensive coverage of wavelet applications in astrophysics, turbulence, meteorology, plasma physics, atomic and solid-state physics, multifractals, biophysics, and mathematical physics.
• Dual focus on continuous and discrete wavelet transforms, explaining when and why to use each approach.
• Practical insights into solving partial differential equations using wavelet methods, a topic of great relevance to computational physics.
• Authoritative contributors who are leading researchers in their respective domains, ensuring cutting-edge content.
• Clear exposition with mathematical rigor balanced by physical intuition, making it accessible to graduate students and advanced undergraduates.

Inside the Book

The book is structured into self-contained chapters, each addressing a specific field of application. Early chapters lay the foundation by explaining the wavelet transform, its properties, and its relationship to other transforms such as the windowed Fourier transform. Subsequent chapters delve into case studies: analyzing turbulent flows, detecting gravitational waves in astrophysics, studying plasma instabilities, characterizing atomic spectra, and modeling complex systems in biophysics such as heart rate variability and neural signals. The final chapters explore multifractal analysis and mathematical physics, including the numerical solution of differential equations. Numerous figures and examples illustrate the concepts, and each chapter includes references for further reading.
