Periods of tropical Calabi--Yau hypersurfaces

摘要:

本文考虑穿孔圆盘$D \setminus \{ 0\}$上由复曲面族Calabi-Yau超曲面定义的Iritani的Hodge结构的剩余B-模型变差.它自然地扩展到整个磁盘$D$上的极化Hodge结构的对数变化。通过将其限制到原点,我们得到了标准对数点上的极化对数Hodge结构(PLH)。在本文中,我们描述的PLH的整体仿射结构的对偶交叉复杂的环面退化的Gros-Siebert计划。

英文摘要:

We consider the residual B-model variation of Hodge structure of Iritani defined by a family of toric Calabi--Yau hypersurfaces over a punctured disk $D \setminus \{ 0\}$. It is naturally extended to a logarithmic variation of polarized Hodge structure of Kato--Usui on the whole disk $D$. By restricting it to the origin, we obtain a polarized logarithmic Hodge structure (PLH) on the standard log point. In this paper, we describe the PLH in terms of the integral affine structure of the dual intersection complex of the toric degeneration in the Gross--Siebert program.
