Résumé
Abstract

Nous étudions le problème de Neumann pour un opérateur élliptique de type Leray–Lions dans un domaine $Ω^{(s)} = Ω \ F^{(s)}$ , $s = 1, 2, \dots$ , où Ω est un ouvert dans $R^{n}$ $(n ⩾ 3)$ , $F^{(s)}$ est un ensemble fermé situé au voisinage d'une variété differentiable Γ de dimension $(n - 1)$ à l'intérieur de Ω. Nous étudions the comportement asymptotique de $u^{(s)}$ quand $F^{(s)}$ converge vers Γ dans un sens approprié.

We investigate the Neumann problem for a nonlinear elliptic operator of Leray–Lions type in $Ω^{(s)} = Ω \ F^{(s)}$ , $s = 1, 2, \dots$ , where Ω is a domain in $R^{n}$ $(n ⩾ 3)$ , $F^{(s)}$ is a closed set located in the neighborhood of a $(n - 1)$ -dimensional manifold Γ lying inside Ω. We study the asymptotic behavior of $u^{(s)}$ as $s \to \infty$ , when the set $F^{(s)}$ tends to Γ.
