Title: Failure of the amalgamation property for definable types
Abstract: In recent joint work with Pablo Cubides Kovacsics and Jinhe Ye on beautiful pairs in the unstable context, the amalgamation property (AP) for the class of global definable types plays a key role. In the talk, we will first indicate some important cases in which AP holds, and we will then present the construction of examples of theories - some even NIP - obtained in joint work with Rosario Mennuni, where AP fails.
