A co-publication of the AMS and Centre de Recherches Mathématiques

This work is based on a series of thematic workshops on the theory of wavelets
and the theory of splines. Important applications are included. The volume is
divided into four parts: Spline Functions, Theory of Wavelets, Wavelets in
Physics, and Splines and Wavelets in Statistics.

Part one presents the broad spectrum of current research in the theory and
applications of spline functions. Theory ranges from classical univariate
spline approximation to an abstract framework for multivariate spline
interpolation. Applications include scattered-data interpolation, differential
equations and various techniques in CAGD.

Part two considers two developments in subdivision schemes; one for uniform
regularity and the other for irregular situations. The latter includes
construction of multidimensional wavelet bases and determination of bases with
a given time frequency localization.

In part three, the multifractal formalism is extended to fractal functions
involving oscillating singularites. There is a review of a method of
quantization of classical systems based on the theory of coherent
states. Wavelets are applied in the domains of atomic, molecular and
condensed-matter physics.

In part four, ways in which wavelets can be used to solve important function
estimation problems in statistics are shown. Different wavelet estimators are
proposed in the following distinct cases: functions with discontinuities,
errors that are no longer Gaussian, wavelet estimation with robustness, and
error distribution that is no longer stationary.

Some of the contributions in this volume are current research results not
previously available in monograph form. The volume features many applications
and interesting new theoretical developments. Readers will find powerful
methods for studying irregularities in mathematics, physics, and statistics.

Titles in this series are co-published with the Centre de Recherches Mathématiques.
