The authors give a review on algorithms for the construction of orthonormal bases of wavelets and on the main properties of the decomposition of a function with respect to these bases. This paper shows how to use these bases in order to study large classes of operators. Theoretical and numerical applications for the resolution of partial differential equations (Dirichlet boundary problems and evolution partial differential equations) are presented.
This paper is essentially self-contained. Many results are given in a simplified form, or their proofs are just sketched. The authors also mention many open problems related to the wavelet decomposition and its applications. Some numerical tests are also included.
