Résumé

In this paper we study the problem $(0.1) \{\begin{matrix} - Δ u = {| u |}^{ϵ} u & in Ω \\ u = 0 & on \partial Ω \end{matrix}$ where $Ω$ is a smooth bounded domain of $ℝ^{N}$ , $N \geq 1$ , $ϵ > 0$ . We will show that, under some assumptions, the solutions to (0.1) are close to suitable linear combinations of eigenfunctions of the problem $\{\begin{matrix} - Δ u = λ u & in Ω \\ u = 0 & on \partial Ω \end{matrix}$ .
