Abstract: | Summary Numerical approximation of a parabolic control problem with a Neumann boundary condition control is considered. The observation
is the final state. The numerical approximation is based on backward discretization with respect to time and a Galerkin method
in the space variables. Optimal (except for a logarithmic term) L2 error estimates are derived for the optimal state. Certain error estimates for the optimal control are also given.
