I will talk about biholomorphic and bimeromorphic automorphisms of hyperkahler manifolds. Oguiso has conjectured that this groups are finitely generated and he proved this in non-projective case. Using an action of these groups on some non-positively curved space, we immediately deduce many of their properties in projective case, including finite representation. This is joint work with E. Yasinsky.
