| Jul 16, 2019 at 11:04 | comment | added | Peter | Great! The section is a homomorphism in the application that I have in mind, which is probably why I got that mixed up. | |

| Jul 15, 2019 at 13:36 | comment | added | Peter | Thank you for the answer! I guess we could use the section $\sigma: H \rightarrow \hat{G}|_{H}$ to describe the right action $\hat{G} \times H \rightarrow \hat{G}$ explicitly as $(\hat{g},h) \mapsto \hat{g} \sigma(h)$, correct? | |
