Wavelet Stabilization and Preconditioning for Domain Decomposition
S. Bertoluzza and A. Kunoth
The aim of this paper is to propose a stabilization technique in order
to circumvent the two
inf--sup conditions needed for stability of the discretization
of the Three Fields Formulation for domain decomposition
methods. Realization of this technique in
terms of wavelets is presented. Furthermore, the resulting discrete problem
is shown to admit an asymptotically optimal preconditioner also
based on wavelets.
