阿贝尔纤维、弦结和通量/几何对偶

Abelian Fibrations, String Junctions, and Flux/Geometry Duality

Ron Donagi, Peng Gao, Michael B. Schulz

摘要:

在以前的工作中,我们证明了保通量N=2超对称的IIB型T^6/Z_2定向折叠与交换曲面(T^4)上的一类纯几何IIA型紧化是对偶的.我们提供了两个明确的建设所产生的卡-丘双。第一种是基于单值的描述,类似于通过7-膜和弦联结对卡-丘几何进行的F-理论编码,除了T^4纤维而不是T^2纤维。第二种是显式代数几何构造,其中T^4纤维作为亏格2曲线族的雅可比环面出现。这种改进的描述的对偶映射将是一个有用的工具,以扩大我们的理解翘曲紧化。我们勾勒应用程序的相关工作,以定义扭曲卡鲁扎-克莱因约化在环面orientifolds,并检查修改后的规则D-膜瞬子零模计数由于通量和其他D-膜的存在。所构造的Calabi-Yau流形的非平凡基本群在杂化模型的建立中也有潜在的应用。

英文摘要:

In previous work, it was argued that the type IIB T^6/Z_2 orientifold with a choice of flux preserving N=2 supersymmetry is dual to a class of purely geometric type IIA compactifications on abelian surface (T^4) fibered Calabi-Yau threefolds. We provide two explicit constructions of the resulting Calabi-Yau duals. The first is a monodromy based description, analogous to F-theory encoding of Calabi-Yau geometry via 7-branes and string junctions, except for T^4 rather than T^2 fibers. The second is an explicit algebro-geometric construction in which the T^4 fibers arise as the Jacobian tori of a family of genus-2 curves. This improved description of the duality map will be a useful tool to extend our understanding of warped compactifications. We sketch applications to related work to define warped Kaluza-Klein reduction in toroidal orientifolds, and to check the modified rules for D-brane instanton zero mode counting due to the presence of flux and other D-branes. The nontrivial fundamental groups of the Calabi-Yau manifolds constructed also have potential applications to heterotic model building.
