We demonstrate that the fusion algebra of conformal defects of a two-dimensional conformal field theory contains information about the internal symmetries of the theory and allows one to read off generalizations of Kramers-Wannier duality. We illustrate the general mechanism in the examples of the Ising model and the three-state Potts model.
我们证明,二维共形场论的共形缺陷融合代数包含有关该理论内部对称性的信息,并允许人们读出克莱默斯 - 万尼尔对偶性的推广。我们在伊辛模型和三态Potts模型的例子中说明了一般机制。
