Abstract
We prove L p Poincaré inequalities with suitable dimension free constants for functions on the discrete cube −1 1 n As well known such inequalities for p an even integer allow to recover an exponential inequality hence the concentration phenomenon first obtained by Bobkov and Götze We also get inequalities between the L p norms of leftvert nabla frightvert and Delta alpha falpha 0 moreover L p spaces may be replaced by more general ones Similar results hold true replacing functions on the cube by matrices in the algebra spanned by n fermions and the L p norm by the Schatten norm C p
