On polarization types of Lagrangian fibrations
Published 2015-01-19Version 1
The generic fiber of a Lagrangian fibration is an abelian variety. This fact is used to associate to each Lagrangian fibration a polarization type which comes from a polarization on a generic fiber. It follows that this polarization type stays constant in a family of Lagrangian fibrations i.e. it is a deformation invariant. Conjecturally the polarization type should only depend on the deformation type of the total space. Indeed, we prove that the polarization type of K3^[n]-type fibrations is always principal.
