Spectral methods for singular perturbation problems

Wilhelm Heinrichs (1994)

Applications of Mathematics

Similarity:

We study spectral discretizations for singular perturbation problems. A special technique of stabilization for the spectral method is proposed. Boundary layer problems are accurately solved by a domain decomposition method. An effective iterative method for the solution of spectral systems is proposed. Suitable components for a multigrid method are presented.
