Resumo

I will talk about automorphisms of hyperkähler manifolds. We prove that the group of bimeromorphic and biholomorphic self-maps of any hyperkähler manifold is finitely presented, answering the question of K. Oguiso. Also, I will discuss Jordan property, in particular, groups $\mathrm{Aut}(M)$ and $\mathrm{Bir}(M)$ have bounded finite subgroups. This is joint work with E. Yasinsky.
