Abstract: In this talk we consider a pointwise tracking optimal control problem for a semilinear elliptic partial differential equation. We derive the existence of optimal solutions and analyze first- and, necessary and sufficient, second-order optimality conditions. Two strategies of discretization are devised to approximate a solution of the optimal control problem: a semidiscrete scheme where the control variable is not discretized and a fully discrete scheme where the control variable is discretized with piecewise constant functions. For both solution techniques, we analyze convergence properties of discretizations and derive error estimates.
