Résumé

In this paper, we use

Γ

-convergence techniques to study the following variational problem

S_{ε}^{F} (Ω) : = sup \{ε^{- 2^{*}} \int_{Ω} F (u) d x : \int_{Ω} {| \nabla u |}^{2} d x \leq ε^{2}, u = 0 on \partial Ω\},

where

0 \leq F (t) \leq {| t |}^{2^{*}}

, with

2^{*} = \frac{2 n}{n - 2}

, and

Ω

is a bounded domain of

ℝ^{n}

n \geq 3

. We obtain a

Γ

-convergence result, on which one can easily read the usual concentration phenomena arising in critical growth problems. We extend the result to a non-homogeneous version of problem

S_{ε}^{F} (Ω)

. Finally, a second order expansion in

Γ

-convergence permits to identify the concentration points of the maximizing sequences, also in some non-homogeneous case.
