Abstract:

In this article, we develop a quadratic $C^{0}$ interior penalty method for the distributed optimal control problem governed by a second order elliptic partial differential equation (PDE) in nondivergence form. We derive both a priori and a posteriori error estimates. The theoretical results are illustrated by numerical experiments.
