Multiscale methods for pseudodifferential equations. (English) Zbl 0788.65112

Schumaker, Larry L. (ed.) et al., Recent advances in wavelet analysis. Boston, MA: Academic Press, Inc.. Wavelet Anal. Appl. 3, 191-235 (1994).
Without giving proofs the authors summarize their papers concerning the use of wavelets in the fast solution of linear pseudo-differential equations enclosing boundary integral equations as an important ingredient.
For the periodic case they consider numerical methods as Galerkin-Petrov or collocation methods in a unified way. Main topics are stability and error analysis in nested trial spaces of wavelets and preconditioning and matrix compression by changing to multiscale bases. Finally, the authors discuss the numerical effort of their approach.
