There are more anomalies which have different descriptions, for instance they do not have to live on a space $\mathcal{A}/\mathcal{G}$ of gauge equivalence classes. | |

| Apr 27, 2020 at 15:11 | comment | added | annie marie cœur | Thanks voted up, so in one sentence, how is the anomaly in QFT in physics = determinant line bundle? Or is that a class in $H^2(\mathcal{A}/\mathcal{G};\mathbb{Z})$? | |
