Sep 10, 2021 at 13:02 | comment | added | Marc Hoyois | I mean that there is a $G$-equivariant isomorphism $P\times_XP\simeq G\times P$ over $P$. This is a local trivialisation of your bundle, since $P\to X$ is a covering. | |
Sep 8, 2021 at 19:53 | comment | added | Dat Minh Ha | @MarcHoyois Could you be a bit more specific ? What do you mean by "pulling $P \to X$ back along $P \to X$" ? | |

Sep 8, 2021 at 18:46 | comment | added | Marc Hoyois | The bundle $P\to X$ becomes trivial after pulling back along the effective epimorphism $P\to X$, since $P\to X\to BG$ factors through the base point. | |
