In this talk we present a block-diagonal preconditioner for the discretized
distributed optimal control problem of the Stokes equations. Using this in
pre- conditioned Krylov subspace methods results in mesh-independent and
robust (i.e.: parameter-independent) convergence rates. Numerical examples
are given, which illustrate the theoretical results.
