椭圆纤维Calabi-Yau三重X的Mordell-Weil群包含了关于X上紧化F-理论得到的六维理论的交换扇区的信息。在考察了广义F理论真空的阿贝尔反常系数矩阵和U(1)电荷量子化条件的特征之后,我们研究了Mordell-Weil秩为1的CalabiYau三重群,作为更详细地理解Mordell-Weil三重群特征的第一步.特别是,我们生成了一类有趣的具有U(1)规范对称性的F理论模型,它们与电荷1和2都有关系。反常方程--它将截面的Néron-Tate高度与截面和流形的纤维有理曲线之间的相交数联系起来--在我们的分析中充当了一个重要工具。
A bstractThe Mordell-Weil group of an elliptically fibered Calabi-Yau threefold X contains information about the abelian sector of the six-dimensional theory obtained by compactifying F-theory on X. After examining features of the abelian anomaly coefficient matrix and U(1) charge quantization conditions of general F-theory vacua, we study CalabiYau threefolds with Mordell-Weil rank-one as a first step towards understanding the features of the Mordell-Weil group of threefolds in more detail. In particular, we generate an interesting class of F-theory models with U(1) gauge symmetry that have matter with both charges 1 and 2. The anomaly equations — which relate the Néron-Tate height of a section to intersection numbers between the section and fibral rational curves of the manifold — serve as an important tool in our analysis.
