| Apr 30, 2018 at 6:09 | comment | added | David Ketcheson | If $\|\cdot\|=\|\cdot\|_2$ and $A, \tilde{A}$ are normal, then $c_A=c_\tilde{A}=1$, so this would be a complete answer (that was the motivation for my comment above). Even if $\tilde{A}$ is not guaranteed to be normal, but $A$ is and $\tilde{A}-A$ is small, then a reasonable bound could be obtained. | |
