| May 3, 2020 at 8:12 | comment | added | Uri Bader | Thanks, Mikael, I should have remembered that you had this figured out. I incorporated this into my answer for the benefit of possible future readers. I hope you don't mind... | |

| Apr 30, 2020 at 13:00 | comment | added | YCor | Actually that at the QI-level the extension $Z\to G\to G/Z$ is trivial (and hence represented by a bounded 2-cocycle) is essentially immediate, using that $Z$ is discrete and that $G/Z$ has a simply connected closed cocompact (solvable) subgroup (this is why I used $T$ in my sketch of argument as a comment to Uri's answer). | |
