Title:Discretization of Stokes type Systems without the LBB condition
Seminar:CCMA PDEs and Numerical Methods Seminar Series
Speaker:Constantin Bacuta, Univ. of Delaware
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.
