Olof B. Widlund

Professor of Computer Science and Mathematics

Throughout his career, Olof Widlund has focused on numerical algorithms for partial differential equations. His primary concern has been new algorithms and mathematical tools for their analysis. In recent years, with his students and other associates, he has concentrated his efforts on domain decomposition algorithms for the large linear systems of algebraic equations that arise in many computational continuum mechanics problems, for example in fluid dynamics and elasticity. These algorithms use a preconditioned conjugate gradient approach and they are designed with parallel and distributed computers in mind. A main challenge is to overcome the potential computational bottleneck arising because the solutions of the linear systems depend on the data everywhere in the region.

These algorithms are being increasingly accepted by the user community and their usefulness on loosely coupled systems has been demonstrated in several careful experimental studies.

Since 1989, nine students have completed doctorates in this field of research.
