关于拉格朗日纤维化的极化类型

On polarization types of Lagrangian fibrations

Benjamin Wieneck

摘要:

不可约全纯辛流形上的拉格朗日纤维化的通有纤维是一个阿贝尔簇。将偏振类型与来自普通光纤上的偏振的这种拉格朗日纤维化相关联。我们证明了这种偏振类型是恒定的拉格朗日纤维化的家庭。进一步,我们确定了K3^[n]型纤维化的偏振类型,并推测偏振类型只取决于全空间的形变类型.

英文摘要:

The generic fiber of a Lagrangian fibration on an irreducible holomorphic symplectic manifold is an abelian variety. Associate a polarization type to such Lagrangian fibrations coming from polarizations on a generic fiber. We prove that this polarization type is constant in families of Lagrangian fibrations. Further, we determine the polarization type of K3^[n]-type fibrations and conjecture that the polarization type should only depend on the deformation type of the total space.
