The case of bounded extremal domains was completely solved by J. Serrin in 1971, and the ball is the unique such domain. Instead, the case of unbounded domains is far from being completely understood. In this talk we give a rigidity result in dimension 2, and also a construction of a nontrivial extremal domain in the form of a exterior domain.
This is joint work with Antonio Ros (U. Granada) and Pieralberto Sicbaldi (U. Granada and U. Aix Marseille).
