In my second example, it's possible to approximate the central support by a finite sum to whatever precision you like (in $\|\cdot\|_2$), but you will not be able get the central support on the nose with a finite sum. | |
| Nov 15, 2015 at 19:42 | comment | added | John N. | I am sorry, I used the wrong symbol: I should have used $\preceq$ instead of $\leq$. I'll correct my question. The property I was referring in my question was written in the paper AN INVITATION TO VON NEUMANN ALGEBRAS, Houdayer (page 18, fourth line from the bottom of the page) and if I understood correctly there aren't assumptions on the centre, so I don't know if I missed something in your answer and/or in the paper. Thanks for the help. | |
