论文摘要
以M理论设计的量子场理论可以具有2组对称性，以非平凡的方式混合0形式和1形对称背景。在本文中，我们开发了从M理论背景的边界几何形状确定2组结构的方法。我们说明了这些方法是在普通和广义的calabi-yau锥体上引起的5D理论，包括所产生理论是非拉格朗日的情况。我们的结果证实并阐明了几何工程的2组结果。
Quantum Field Theories engineered in M-theory can have 2-group symmetries, mixing 0-form and 1-form symmetry backgrounds in non-trivial ways. In this paper we develop methods for determining the 2-group structure from the boundary geometry of the M-theory background. We illustrate these methods in the case of 5d theories arising from M-theory on ordinary and generalised toric Calabi-Yau cones, including cases in which the resulting theory is non-Lagrangian. Our results confirm and elucidate previous results on 2-groups from geometric engineering.
