Soane, Ana MarieDraganescu, Andrei2018-04-102018-04-102018http://hdl.handle.net/11603/7929In this work we construct multigrid preconditioners to be used in the Newton-Krylov method for a distributed optimal control problem constrained by the stationary Navier-Stokes equations. These preconditioners are shown to be of optimal order with respect to the convergence properties of the discrete methods use to solve the Navier-Stokes equations.25 pagesen-USThis item may be protected under Title 17 of the U.S. Copyright Law.
