Soit Ω un domaine à bord Lipschitz d'une variété riemannienne compacte (M,g) et p>1. Nous montrons qu'on peut rendre le volume de M arbitrairement proche du volume de (Ω,g) tout en gardant la première valeur propre du p-Laplacien sur M uniformement minorée en termes de la première valeur propre du problème de Neumann pour le p-Laplacien sur (Ω,g).

Let Ω be a domain with Lipschitzian boundary of a compact Riemannian manifold (M,g) and p>1. We prove that we can make the volume of M arbitrarily close to the volume of (Ω,g) while the first eigenvalue of the p-Laplacian on M remains uniformly bounded from below in terms of the the first eigenvalue of the Neumann problem for the p-Laplacian on (Ω,g).
