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 ( ), and in the singular ( ) range.

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  , ainsi bien que dans le cas singulier  .
