| Feb 24, 2022 at 0:21 | comment | added | David Ben-Zvi | Thanks @AndréHenriques , that was a bit of nonsense - I meant to say inertial action of $J$, which comes from an action of $BJ$ on$\mathfrak g/G$ | |
| Feb 24, 2022 at 0:05 | comment | added | André Henriques | I'm not sure how an action of a (family of) groups on a stack can produce 2-stackiness... When you say $J$ acts on $\mathfrak g/G$, did you maybe intend to say $BJ$ acts on $\mathfrak g/G$? | |
