| Jan 7, 2022 at 22:14 | comment | added | Carlo Beenakker | 1) yes; 2) just look directly below the equation 14 you are citing; the expectation value is there. | |
| Jan 7, 2022 at 22:06 | comment | added | Spring Breeze | @CarloBeenakker 1- Are you saying that the trace of square root of the covariance matrix is the same as the 2-norm? 2- What does expected value has to due with the inequality? | |
| Jan 7, 2022 at 21:27 | comment | added | Carlo Beenakker | you should take the expectation value on the left-hand-side of your inequality; isn't this then just the statement that $\|x\|_\infty\leq \|x\|_2$ ? | |
