| Mar 1, 2011 at 13:11 | comment | added | Łukasz Grabowski | Your proof shows also that $1$ on the right-hand side can be replaced by $|f|_1/|f|$, where $|f|_1$ is the $l^1$-norm of $f$ and $|f|$ is the operator norm of $f$. Which can be interpreted as saying that non-amenable groups are more "Heisenberg-uncertain" than ameanable groups :-). | |
