The main purpose of this paper is to analyze the asymptotic behaviour of the ground state solution of Hénon equation −Δu=|x|αup−1 in Ω, u=0 on ∂Ω (Ω Rn is a ball centered at the origin). It proved that for p close to 2*= 2n/(n−2) (n≥3), the ground state solution up has a unique maximum point xp and dist(xp, ∂Ω)→0 as p→2*. The asymptotic behaviour of up is also given, which deduces that the ground state solution is non-radial.

Let Ω RN be a smooth bounded domain such that 0 ∈Ω, N≥7, 0≤s<2, 2*(s)=2(N−s)/(N−2). We prove the existence of sign-changing solutions for the singular critical problem −Δu−μ(u/|x|2)=(|u|2∗(s)−2/|x|s)u+λu with Dirichlet boundary condition on Ω for suitable positive parameters λ and μ.

We study the radially symmetric Schrödinger equation-ε2△u+V(|x|)u=W(|x|)up, u>0, u∈H1(RN), with N≥1, ε>0 and p>1. As ε→0, we prove the existence of positive radially symmetric solutions concentrating simultaneously on k spheres. The radii are localized near non-degenerate critical points of the function Γ(r)=rN−1[V(r)]p+1/p−1−1/2[W(r)]−2/p−1.
