In this paper, we prove the existence of infinitely many solutions for the following elliptic problem with critical Sobolev growth:where Ω is a bounded domain in R N with C 3 boundary, N 3, ν is the outward unit normal of ∂Ω, 2 * = 2N N−2 , and g(t) = μ|t| p−2 t − t, or g(t) = μt, where p ∈ (2, 2 * ), μ > 0 are constants.We obtain the existence of infinitely many solutions under certain assumptions on N, p and ∂Ω. In particular, if g(t) = μt with μ > 0, N 7, and Ω is a strictly convex domain, then the problem has infinitely many solutions.
