如果一个纤维化的所有光滑纤维同构于一个固定簇,则称该纤维化是等平凡的。我们分类的椭圆K3曲面是isovarious,并使用它们来构建拉格朗日纤维化isovarious。然后,我们修改的建设,以产生新的例子全纯辛orbifolds,也承认isovarious拉格朗日纤维化。
A fibration is said to be isotrivial if all of its smooth fibres are isomorphic to a single fixed variety. We classify the elliptic K3 surfaces that are isotrivial, and use them to construct Lagrangian fibrations that are isotrivial. We then modify the construction to produce new examples of holomorphic symplectic orbifolds, that also admit isotrivial Lagrangian fibrations.
