Invertible projective 2-representations from invertible 2d TQFTs with defects
Domenico Fiorenza, Chetan Vuppulury
We investigate invertible projective representations and their 2-categorical analogues using the language of TQFTs with defects. The main result is a freeness property for invertib…

Projective and anomalous representations of categories and their linearizations
Domenico Fiorenza, Chetan Vuppulury
We invesigate the relation between projective and anomalous representations of categories, and show how to any anomaly one can associate an…
