Jun 18 Automorphisms of hyperkahler manifolds and fractal
geometry of hyperbolic groups Misha Verbitsky (IMPA)
Tuesdays, 14:30-15:30, in Math -101
A hyperkahler manifold is a compact holomorphically
symplectic manifold of Kahler type. We are interested in
hyperkahler manifolds of maximal holonomy, that is, ones
which are not flat and not decomposed as a product after
passing to s finite covering.
The group of automorphisms of such a manifold has a
geometric interpretation: it is a fundamental group of a
certain hyperbolic polyhedral space. I will explain how to
interpret the boundary of this hyperbolic group as the
boundary of the ample cone of the hyperkahler
manifold. This allows us to use the fractal geometry of
the limit sets of a hyperbolic action to obtain results of
hyperkahler geometry.

Title: Bogomolov-Tian-Todorov for holomorphic symplectic manifolds

Bogomolov-Tian-Todorov theorem claims that the deformation
space of a Calabi-Yau manifold M is locally biholomorphic
to the vector space $H^{n-1, 1}(M)$. I would explain how to
build a local deformation theory for manifolds admitting a
holomorphic symplectic structure (not necessarily Kahler),
significantly simplifying the proof of
Bogomolov-Tian-Todorov theorem for K3 surfaces.
