| Mar 15, 2020 at 15:38 | comment | added | paul garrett | Right: with a non-degenerate $E$-one-dimensional space, the corresponding unitary group has no proper parabolics... because it has no non-trivial isotropic subspaces. | |
| Mar 15, 2020 at 5:53 | comment | added | Monty | @Paul, from your comment, I think that $U(1)$ has no proper parabolic subgroup. Right? | |
| Mar 15, 2020 at 5:05 | comment | added | Monty | @Paul, You are right! I think there is no proper parabolic and so no proper Iwasawa decomposition. Thank you very much for comment. | |
