Title: The dual Lagrangian fibration of compact hyperKaehler manifolds
Abstract: A compact hyperKaehler manifold is a higher dimensional generalization of a K3 surface. An elliptic fibration of a K3 surface correspondingly generalizes to the socalled Lagrangian fibration of a compact hyperKaehler manifold. It is known that an elliptic fibration of a K3 surface is always selfdual in a certain sense. This turns out to be not the case for higherdimensional Lagrangian fibrations. In this talk, I will propose a construction for the dual Lagrangian fibration of all currently known examples of compact hyperKaehler manifolds, and try to justify this.
