Misha Verbitsky 氏 (ITEP Moscow/IPMU)
Mapping class group for hyperkaehler manifolds
[ 講演概要 ]
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.
