我们研究了膜铺层的方向性。我们阐明了如何通过d5膜电荷守恒来保证规范异常和Witten异常的消去。我们还讨论了膜层与作为规范理论的模空间实现的对偶Calabi-Yau锥之间的关系。提出了膜层中的两种风味d5膜及其对应的基本夸克场的超势，并证明了这些夸克在模空间中的无质量轨迹正确地再现了五膜体系中Calabi-Yau锥对偶中的风味d7膜的世界体积。
We investigate orientifold of brane tilings. We clarify how the cancellations of gauge anomaly and Witten's anomaly are guaranteed by the conservation of the D5-brane charge. We also discuss the relation between brane tilings and the dual Calabi-Yau cones realized as the moduli spaces of gauge theories. Two types of flavor D5-branes in brane tilings and corresponding superpotentials of fundamental quark fields are proposed, and it is shown that the massless loci of these quarks in the moduli space correctly reproduce the worldvolume of flavor D7-branes in the Calabi-Yau cone dual to the fivebrane system.
