摘要翻译:
对于具有全纯n型基的一般型超曲面的单参数族,我们利用热带几何构造开覆盖。证明了归一化后,每一个全纯n型近似支持在一个唯一的开分量上,当参数变大时,这样的对与其全纯n型一起近似于一个Calabi-Yau超曲面。我们还证明了Mikhalkin构造的纤维中的拉格朗日纤维是渐近特殊拉格朗日纤维。由于全纯N型在Calabi-Yau流形的镜像对称性中起着重要作用,我们的结果为理解一般流形的镜像对称性迈出了一步。

英文摘要:
For a one-parameter family of general type hypersurfaces with bases of holomorphic n-forms, we construct open covers using tropical geometry. We show that after normalization, each holomorphic n-form is approximately supported on a unique open component and such a pair approximates a Calabi-Yau hypersurface together with its holomorphic n-form as the parameter becomes large. We also show that the Lagrangian fibers in the fibration constructed by Mikhalkin are asymptotically special Lagrangian. As the holomorphic n-form plays an important role in mirror symmetry for Calabi-Yau manifolds, our results is a step toward understanding mirror symmetry for general type manifolds.
