| Abstract: | In $1+1$d, the fusion category symmetry generalizes the concept of global symmetry. Akin to ordinary global symmetry, the fusion category symmetry can also suffer from 't Hooft anomalies. We describe a criteria of when the 't Hooft anomaly is non-trivial from the data that describes the fusion category. This criteria generalizes the one from [1802.04445]. We also comment on how the anomalous theory couples to a non-invertible TQFT in one dimension higher. |
