Abstract
We prove an explicit formula conjectured recently by Wang and Levin for the anomaly of time-reversal symmetry in ()-dimensional fermionic topological quantum field theories. The crucial step is to determine the cross-cap state in terms of the modular matrix and eigenvalues, generalizing the recent analysis by Barkeshli et al. in the bosonic case.
