Wavelets and Operators

Over the last two years wavelet methods have shown themselves to be of considerable use to harmonic analysts and in particular advances have been made concerning their applications. The strength of wavelet methods lies in their ability to describe local phenomena more accurately than a traditional expansion in sines and cosines can. Thus wavelets are ideal in many fields where an approach to transient behaviour is needed for example in considering acoustic or seismic signals or in image processing. Yves Meyer stands the theory of wavelets firmly upon solid ground by basing his book on the fundamental work of Caldern Zygmund and their collaborators. For anyone who would like an introduction to wavelets this book will prove to be a necessary purchase.
