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.
