Max Hubner, David R. Morrison, Sakura Schafer-Nameki, Yi-Nan Wang

摘要:

在非紧椭圆纤维化的Calabi-Yau流形上实现了F-理论紧化的高阶对称性。这项工作的核心是拓扑结构的边界的非紧椭圆纤维化,以及明确建设的相对2-周期的莱夫谢茨顶针。我们将分析应用到各种椭圆纤维化,包括几何形状的判别椭圆纤维化相交的边界。我们通过从椭圆纤维化出发构造相应的带电线算符,给出了1型对称群的具体实现。作为应用,我们计算了对称拓扑场论在椭圆三重的情况下,这对应于混合异常的5d和6d理论。

英文摘要:

We realize higher-form symmetries in F-theory compactifications on non-compact elliptically fibered Calabi-Yau manifolds. Central to this endeavour is the topology of the boundary of the non-compact elliptic fibration, as well as the explicit construction of relative 2-cycles in terms of Lefschetz thimbles. We apply the analysis to a variety of elliptic fibrations, including geometries where the discriminant of the elliptic fibration intersects the boundary. We provide a concrete realization of the 1-form symmetry group by constructing the associated charged line operator from the elliptic fibration. As an application we compute the symmetry topological field theories in the case of elliptic three-folds, which correspond to mixed anomalies in 5d and 6d theories.
