  • "The Kawamata-Morrison conjecture for the ample cone of a hyper-Kahler variety", mini-cours par Eyal Markman (Université du Massachusetts) lundi 26 mai 15h00-16h00, mercredi 28 mai 10h30-12h00 et 16h00-17h00

    Abstract: This work is joint with Kota Yoshioka. We derive the Kawamata-Morrison conjecture for the ample cone of a projective irreducible holomorphic symplectic manifold from the proven movable cone version of the conjecture and a lower bound on the Beauville-Bogomolov-Fujiki degree of exceptional curve. The latter bound in known in the K3 and generalized Kummer deformation types by work of Bayer-Macri, Yoshioka, and Bayer-Hassett-Tschinkel. Similar results were independently obtained by Amerik and Verbitsky forthe Kahler cone, dropping the projectivity assumption.
