Jan 11, 2017 at 7:48 | comment | added | Kevin Buzzard | You seem to ask two questions -- one "for all $H'$" and one "there exist $H'$". The first one seems trivially false in general because one can set $H'=H$ and you seem to know this so I'm not sure what you're asking. As for the second one, if you can find some $F'/Q_p$ such that $O_{F'}\otimes_{\mathbb{Z}_p}O_E=O_{E'}$ then you can you can base extend along $F'/Q_p$ instead to get a proof. But of course such $F'$ might not exist and my guess is that if it doesn't then you might be in trouble (for example perhaps $H$ is the only choice for $H'$?) | |
