| Apr 18, 2012 at 10:03 | comment | added | Yemon Choi | @Olaf: I meant the particular P in my answer, I thought that was obvious from context | |
| Apr 18, 2012 at 8:43 | comment | added | Olaf Kummers | What do you mean both? One of them can be e.g. $\ell_\infty$. | |
| Apr 18, 2012 at 7:09 | comment | added | Yemon Choi | @Olaf: without thinking about it too hard, I can at least point you to a result of Blower mentioned here mathoverflow.net/questions/12211/… which implies, in particular, that either $P(B(H))$ or $(I-P)(B(H))$ is isomorphic as a Banach space to $B(H)$. I rather suspect both are, but don't see at this moment how one would show this. | |
| Apr 18, 2012 at 6:41 | comment | added | Olaf Kummers | Thanks. How about (Banach) complemented subspaces (Banach) isomorphic to $\mathcal{K}(H)$ or $\mathcal{B}(H)$? | |
