Until now, my research has been focussed on multigrid methods for partial differential equations and on the solution of sparse linear systems. Recently I got involved into the application of wavelet methods in seismology. Room M231 Dept. The Netherlands Postal address Centrum voor Wiskunde en Informatica Dept. Most of the chapters have been published in journals.
Emphasis is on robust coarse grid corrections by means of operator-dependent intergrid transfers.
