Abstract
We are concerned with the nonlinear critical problem -∆u = K(x)u3, u > 0 in Ω, u = 0 on ∂Ω, where Ω is a bounded domain of ℝ4. Under the assumption that K is strictly decreasing in the outward normal direction on ∂Ω and degenerate at its critical points for an order β ∈ (1, 4), we provide a complete description of the lack of compactness of the associated variational problem and we prove an existence result of Bahri-Coron type.
