论文摘要
我们回顾了Orbifold操作在玻色子或费米子上的二维量子场理论上的特性，并描述了控制Orbifold操作组成的“ Orbifold Groupoids”。 Dijkgraaf-Witten类型的三维TQFT将在分析中发挥重要作用。我们简要地讨论了对对称和应用的扩展，以限制RG流。
We review the properties of orbifold operations on two-dimensional quantum field theories, either bosonic or fermionic, and describe the "Orbifold groupoids" which control the composition of orbifold operations. Three-dimensional TQFT's of Dijkgraaf-Witten type will play an important role in the analysis. We briefly discuss the extension to generalized symmetries and applications to constrain RG flows.
