Preconditioning of optimal Dirichlet boundary control problems in energy spaces
Prof. Lorenz JohnJune 14, 2012, 1:30 p.m. S2 416
We consider preconditioning techniques for iterative solution methods applied to the optimality system discretized by finite elements for Dirichlet boundary control problems in appropriate energy spaces. In particular, we focus on the robustness with respect to the mesh size and the cost coefficient. Further, we present some numerical examples which confirm the obtained theoretical results.
