Optimal error estimates and computations for tracking-type control of the instationary Stokes system
We consider an optimal control problem of tracking type for Stokes flows
in two and three space dimensions. The solution is approximated by a
finite element method which is based on the necessary first order
optimality conditions. We prove optimal error estimates for the
resulting semi--discrete scheme and present numerical examples that
confirm our results.
