| Jun 19, 2019 at 6:26 | comment | added | Tyler Lawson | Wonderful, thank you! What I find curious about this is that it uses that the twist $L \otimes L \to L \otimes L$ is the identity for $L$ invertible; I had verified this separately and it was what led me to wonder if the same were true of the twist in the Brauer group. | |
