OPTIMAL A PRIORI ERROR ESTIMATES OF PARABOLIC OPTIMAL CONTROL PROBLEMS WITH POINTWISE CONTROL

In this paper we consider a parabolic optimal control problem with a pointwise (Dirac type) control in space, but variable in time, in two space dimensions. To approximate the problem we use the standard continuous piecewise linear approximation in space and the piecewise constant discontinuous Gale...
