 Title : The dual Lagrangian fibration of hyperKähler manifolds
 Abstract :
A (compact) hyperKähler manifold X is a higher dimensional generalization of a K3 surface. It is often interesting to study its special morphism X > B, called a Lagrangian fibration of X. Any Lagrangian fibration of a K3 surface is always "selfdual", so one does not need to worry about how to construct its dual. This is no longer the case for higherdimensional hyperKähler manifolds and their Lagrangian fibrations. In this talk, I will propose a construction for the dual Lagrangian fibration for all currently known examples of hyperKähler manifolds.
