Valeria Bertini (Technical University Chemnitz): Rational curves on Hyperkähler manifolds
Ort: MPI für Mathematik in den Naturwissenschaften Leipzig, Inselstr. 22, G3 10 (Hörsaal)
Hyperkähler manifolds are the higher dimensional generalization of K3 surfaces, which are a very important and well-understood class of surfaces in algebraic geometry; on projective K3 surfaces, the existence of rational curves is well known thanks to a classical result by Bogomolov and Mumford. I will present the state of the art of the Hyperkähler case, presenting some recent results about the existence of uniruled divisors on some deformation classes of projective Hyperkähler manifolds.
