Plenary talk: Optimal Control of Partial Differential Equations with Nonsmooth Cost Functionals


Over the last several decades tremendous progress in the analysis and numerical treatment of optimal control problems governed by partial differential equations and smooth cost functionals was made.

But in many important applications the cost is non-smooth. This is the case, for instance, for optimal control with sparsity constraints, for minimum effort problems, and for optimal control with switching constraints.

The natural settings of such problems are non-reflexive Banach spaces, which lead to new analytical challenges. The lack of smoothness, on the other hand, demands novel numerical tools for practically solving the resulting infinite dimensional optimization problems. In the talk I serve recent contributions to this exciting topic.
