Mathematik und Informatik

I will present a construction of a special kind of action of a free group on any countable or separable saturated structure, which enjoys a strong form of freeness given by (local) stability theory. This is one of the main ingredients of a proof that automorphism groups of separably categorical structures have Property (T) of Kazhdan.
