Automorphisms of hyperkähler manifolds and groups acting on CAT(0) spaces

Speaker: Nikon Kurnosov, University of Georgia, Athens

Location: Warren Weaver Hall 317

Date: Tuesday, October 9, 2018, 3:30 p.m.

Synopsis:

I will talk about boholomorphic and bimeromorphic automorphisms of projective hyperkahler manifolds. Using an action of these groups on some non-positively curved space, we immediately deduce many of their properties, including finite representation. This is joint work with E. Yasinsky.
