Generic automorphisms of homogeneous structures

Abstract: Automorphism groups of countable first-order structures are Polish groups under the pointwise convergence topology. An automorphism is called generic if its conjugacy class in comeagre. In this talk we focus on generic automorphisms of homogeneous structures, such structures arise as Fraisse limits of amalgamation classes of finite structures. We will present joint work with Itay Kaplan and Tomasz Rzepecki studying generic automorphisms of the countable universal homogeneous meet-tree.
