En utilisant des résultats récents sur l'inégalité de Harnack pour les équations type p-laplacien, on établit des théorèmes de type Liouville pour les solutions de ces équations, dans le cas dégénéré p>2, ainsi bien que dans le cas singulier 1<p<2.

Relying on recent results on Harnack inequalities for equations of p-Laplacian type, we prove Liouville-type estimates for solutions to these equations, both in the degenerate (p>2), and in the singular (1<p<2) range.
