Abstract
Finite element approximations of an elliptic control problem are analyzed. Optimal order estimates are obtained in terms of the mesh size h and the target ψ A computational scheme is derived which allows for the application of the conjugate gradient method. The scheme is implemented and tested on some model problems.Keywords
