| Jan 19, 2019 at 9:26 | comment | added | David Roberts♦ | Sure, you can probably prove it other ways, but this is the quickest way I know with the tools I have that I can prove $\theta$ is a diffeomorphism. $BG$ is a stack, after all, so you might as well use that. YMMV. | |
| Jan 19, 2019 at 9:23 | comment | added | Praphulla Koushik | Thanks. Can this be done with out using "bicategorical localisation"? I thought this is some simple question which has very little to do with stacks and all that... Is the question that serious that it has to be treated with localization and all that? | |
