论文摘要
我们研究了$ 4D $ $ \ $ \ MATHCAL {n} = 1 $量规理论，该理论是通过d-branes在曲奇奇点的东方的d-branes上设计的，在没有引入非紧凑型风味麸皮的情况下取消规格异常。使用二聚体模型技术，我们得出了几何标准，用于确定给定的奇异性是否可以纯粹基于其折叠数据和Erientifold投影的类型来允许无异常的D-Brane配置允许。因此，我们的结果扩展了奇异性的几何特性与相应仪表理论的物理特性之间的字典。
We study $4d$ $\mathcal{N}=1$ gauge theories engineered via D-branes at orientifolds of toric singularities, where gauge anomalies are cancelled without the introduction of non-compact flavor branes. Using dimer model techniques, we derive geometric criteria for establishing whether a given singularity can admit anomaly-free D-brane configurations purely based on its toric data and the type of orientifold projection. Our results therefore extend the dictionary between geometric properties of singularities and physical properties of the corresponding gauge theories.
