Abstract:

In this paper we prove an existence result for the nonlinear elliptic problem:-△u=Ku5, u>0 in Ω, u=0 on ∂Ω, where Ω is a smooth bounded domain of R3 and K is a positive function in Ω. Our method relies on studying its corresponding subcritical approximation problem and then using a topological argument.

Key words: scalar-curvature, critical point, limiting Sobolev exponent, variational problems with lack of compactness, blow up analysis
