TITLE	Reduced Basis a Posteriori Error Bounds for Parametrized Linear-Quadratic Elliptic Optimal Control Problems
AUTHORS	Martin A. Grepl, Mark Kärcher
ABSTRACT	We employ the reduced basis method as a surrogate model for the solution of optimal control problems governed by parametrized partial differential equations (PDEs) and develop rigorous a posteriori error bounds for the error in the optimal control and the associated error in the cost functional. The proposed bounds can be efficiently evaluated in an offline-online computational procedure. We present numerical results that confirm the validity of our approach.
