| Jul 28 at 9:19 | comment | added | YCor | Thanks, I see. So QI rigidity allows to encompass $k_i=2$. | |
| Jul 27 at 23:04 | comment | added | Moishe Kohan | @YCor: Kleiner-Leeb would be an overkill, I use the fact that the automorphism group of a lattice is a bigger lattice, which follows from Mostow (one first passes to a finite index subgroup in $G_i$ to ensure normality). | |
| Jul 27 at 21:41 | comment | added | YCor | When you say "by Mostow rigidity": I know this as a consequence of QI rigidity (it is explicitly stated in one of the Kleiner-Leeb papers), but do not see immediately why it follows from Mostow rigidity. | |
