Résumé
Abstract

Soit Γ un groupe dénombrable infini qui agit naturellement sur $ℓ^{p} (Γ)$ . Nous introduisons une obstruction, proche de la dimension moyenne, au fait que $ℓ^{p} (Γ)$ et $ℓ^{q} (Γ)$ soit Hölder conjugués.

Let Γ be a infinite countable group which acts naturally on $ℓ^{p} (Γ)$ . We introduce a modification of mean dimension which is an obstruction for $ℓ^{p} (Γ)$ and $ℓ^{q} (Γ)$ to be Hölder conjugates.
