Around the cone conjecture for hyperkähler manifolds

Abstract: The Morrison-Kawamata cone conjecture states that the automorphism group of a Calabi-Yau manifold acts with finitely many orbits on the set of faces of its ample cone. I shall sketch its proof in the hyperkähler case with some emphasis on a statement on Lie groups behind it. All results are joint work with Misha Verbitsky.
