| Abstract: | A mapping class group is a group of orientation-preserving diffeomorphisms up to isotopy. I explain how to compute a mapping class group of a hyperkaehler manifold. It is commensurable to an arithmetic lattice in a Lie group SO(n-3,3). This makes it possible to state and prove a new version of Torelli theorem. |
