Title: On automorphism groups of K3 and Enriques surfaces
Abstract: According to the Tits alternative, the automorphism group of a smooth projective surface is either virtually abelian (i.e. it contains an abelian subgroup of finite index) or it contains a free, non-abelian subgroup. By classification of surfaces, the latter can only occur on rational, K3, Enriques or abelian surfaces. I will present a classification of K3 and Enriques surfaces with virtually abelian automorphism groups, focusing on the dynamical properties of their automorphisms. Furthermore, I will present some geometric examples and talk about possible applications.
