February 20 – Thirupathi Gudi: An energy space based approach for the finite element approximation of the Dirichlet boundary control problem.

Thirupathi Gudi: Tuesday 20 February at 3 pm, A415 Inria Paris.
In this talk, we review some approaches for formulating the Dirichlet boundary control problem and then we present a new energy space based approach. We show that this new approach allows high regularity for both optimal control and the optimal state. Using, the optimality conditions at continuous level, we propose a finite element method for numerical solution and derive subsequent error estimates. We show some numerical experiments to illustrate the method.
