| Abstract: |
|---|
| We first present a regularity result for the Stokes system on
polygonal domains. Next, we provide an abstract framework for
discretizing saddle point systems of Stokes type and first order
differential systems. We introduce new algorithms which combine the
inexact Uzawa method at the continuous level with standard multilevel
techniques. The discrete (LBB) stability condition might not be satisfied
and a posteriori error estimates are required only for solutions of
symmetric and positive definite problems. In the end we provide an
application to first order systems and numerical results
supporting the new approach. |
