abstract = {
A distributed optimal control problem for evolutionary Stokes flows is
studied via a pseudocompressibility formulation.
Several results concerning the analysis of the velocity tracking problem are
presented. Semidiscrete finite element error estimates for the corresponding
optimality system are derived based on estimates for the penalized
Stokes problem and the BRR (Brezzi-Rappaz-Raviart) theory. Finally, the
convergence of the solutions of the penalized optimality systems
as ε → 0 is examined.
