In this paper, we study the existence and nonexistence of multiple positive solutions for the inhomogeneous Neumann boundary value problem Δu+up−λu=0, with Dγu=ϕ(x), (*) under some assumptions on the boundary ∂Ω and the function ϕ(x). For ϕ(x)≥0, ϕ(x) 0, ϕ(x) ∈Cα( ), it is shown that there exists a constant λ*>0 such that problem (*) possesses at least two positive solutions if λ∈ (λ*,∞) and at least one positive solution if λ=λ*. Furthermore, there are no positive solutions for problem (*) if λ∈ (-∞, λ*).

【期刊论文】The asymptotic behaviour of the ground state solutions for Hénon equation

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.
