| Jun 24, 2015 at 21:12 | comment | added | student | I checked my proof,and found a mistake. I used a result here link.springer.com/article/10.1007/BF01263495, but I messed up with the direction of inequalities. Just one thing I'm not quite sure about, is the sentence "This means that total sum of projections is infinite". | |
