Neumann problem for a quasilinear elliptic equation in a varying domain

We investigate the Neumann problem for a nonlinear elliptic operator of Leray–Lions type in ${\Omega }^{(s)}=\Omega \backslash F^{(s)}$, $s=1,2,\dots$, where Ω is a domain in ${\mathbf{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. To cite this article: M. Sango, C. R. Acad. Sci. Paris, Ser. I 342 (2006).
