Preprint: Biorthogonal Wavelets and Multigrid

The following preprint is available:

Biorthogonal Wavelets and Multigrid
Stephan Dahlke and Angela Kunoth

Abstract:
We will be concerned with the solution of an elliptic boundary value
problem in one dimension with polynomial coefficients. In a Galerkin
approach, we employ biorthogonal wavelets adapted to a differential
operator with constant coefficients, and use the refinement equations
to set up the system of linear equations with exact entries (up to
round-off). For the solution of the linear equation, we construct
a biorthogonal two-grid method with intergrid operators stemming
from wavelet-type operators adapted to the problem.
