The finite element approximation of an optimal control problem is considered. Some a posteriori error estimates for the finite element approximation of the optimal control problem are derived. These estimates can be used as error indicators in developing adaptive finite element schemes for control problems. Ruxandra Stavre (Bucure\c{s}ti)
