Lara B. Anderson, Xin Gao, James Gray, Seung-Joo Lee

摘要:

在这项工作中,我们探讨的物理相关的卡-丘(CY)n-折叠,可以被描述为纤维化在一个以上的方式。从不同维度的F理论真空开始,我们考虑M理论、IIA型和杂合弦论的极限/对偶。我们的结果包括许多M-/F-理论对应,其中不同的F-理论真空-与相同的CY n倍的不同椭圆纤维化-在一维下产生相同的M-理论极限。例子包括6维理论与阿贝尔、非阿贝尔和超共形结构之间的5维对应,以及更高秩的莫德尔-韦伊几何的例子。此外,在杂种优势/F-理论对偶的背景下,我们研究了多个K3和椭圆纤维化在8维,6维和4维理论中已知和新的弦对偶中所起的作用。在这里,我们系统地总结了嵌套纤维化结构和评论的作用,他们在T-对偶,镜像对称,和4维紧化的F-理论与G-流量。对偶结构的这种研究是通过在一篇配套论文[1]中开发的几何工具而成为可能的。

英文摘要:

In this work we explore the physics associated to Calabi-Yau (CY) n-folds that can be described as a fibration in more than one way. Beginning with F-theory vacua in various dimensions, we consider limits/dualities with M-theory, type IIA, and heterotic string theories. Our results include many M-/F-theory correspondences in which distinct F-theory vacua - associated to different elliptic fibrations of the same CY n-fold - give rise to the same M-theory limit in one dimension lower. Examples include 5-dimensional correspondences between 6-dimensional theories with Abelian, non-Abelian and superconformal structure, as well as examples of higher rank Mordell-Weil geometries. In addition, in the context of heterotic/F-theory duality, we investigate the role played by multiple K3- and elliptic fibrations in known and novel string dualities in 8-, 6- and 4-dimensional theories. Here we systematically summarize nested fibration structures and comment on the roles they play in T-duality, mirror symmetry, and 4-dimensional compactifications of F-theory with G-flux. This investigation of duality structures is made possible by geometric tools developed in a companion paper [1].
