    Profile of solutions for nonlocal equations with critical and supercritical nonlinearities

    We study the fractional Laplacian problem

    (I𝜀){(Δ)su=up𝜀uqinΩ,u>0inΩ,u=0inN\Ω,uHs(Ω)Lq+1(Ω);
    where s(0,1), q>pN+2sN2s and 𝜀>0 is a parameter. Here, ΩN is a bounded star-shaped domain with smooth boundary and N>2s. We establish existence of a variational positive solution u𝜀 and characterize the asymptotic behavior of u𝜀 as 𝜀0. When p=N+2sN2s, we describe how the solution u𝜀 blows up at an interior point of Ω. Furthermore, we prove the local uniqueness of solution of the above problem when Ω is a convex symmetric domain of N with N>4s and p=N+2sN2s.
