Jun 20, 2010 at 9:35 comment added Pietro Majer Well I have added an edit, I hope it's clear. To see the picture, one can exaggerate things, taking the $l^\infty$ and $l^1$ norms instead of the $l^3$ and $l^{3/2}$. Actually I'd say that the inequality is generically never true for any pairs of dual norms, with the only exception of the Euclidean case.
