Clarkson inequality


The Clarkson inequality says that for all f,gLp, for 2p< we have:

f+g2pp+f-g2pp12(fpp+gpp).

The inequalityMathworldPlanetmath can be used to prove that Lp space is uniformly convex for 2p<.

Remark. If 1<p<2, then the Clarkson inequality becomes:

f+g2pq+f-g2pq(12fpp+12gpp)1p-1

.

for functions f,gLp, where q=pp-1.
