一个僵硬的卡拉比-尤3倍

A rigid Calabi--Yau 3-fold

Sara Angela Filippini, Alice Garbagnati

摘要:

本文的目的是分析由$E^3$的商得到的刚性Calabi-Yau三重$\mathcal{Z}$的一些几何性质,其中$E$是一种特殊的椭圆曲线.我们描述了$\mathcal{Z}$的上同调,并给出了$Pic(\mathcal{Z})$上三线性形式的一个简单公式.我们描述了$\mathcal{Z}$的一些投影模型,并将这些模型与它的广义镜像联系起来。奇异模型的光滑化是一个Calabi-Yau三重光滑化,其Hodge数很小,这是以前所不知道的。

英文摘要:

The aim of this paper is to analyze some geometric properties of the rigid Calabi--Yau threefold $\mathcal{Z}$ obtained by a quotient of $E^3$, where $E$ is a specific elliptic curve. We describe the cohomology of $\mathcal{Z}$ and give a simple formula for the trilinear form on $Pic(\mathcal{Z})$. We describe some projective models of $\mathcal{Z}$ and relate these to its generalized mirror. A smoothing of a singular model is a Calabi--Yau threefold with small Hodge numbers which was not known before.
