在本注中,我们考虑以下问题−Δ u=(1+ g (x)) u N+ 2 N−2,u> 0在B中,u= 0在∂B中,其中N≥3,B N是以原点为中心的单位球,g (x)是径向的Hölder连续函数,使得g(0)= 0。利用浓度紧性分析和Pohozaev恒等式,用变分方法证明了径向解的存在性和不存在性。
In this note, we consider the following problem− Δ u=(1+ g (x)) u N+ 2 N− 2, u> 0 in B, u= 0 on∂ B, where N≥ 3 and B⊂ ℝ N is the unit ball centered at the origin and g (x) is a radial Hölder continuous function such that g (0)= 0. We prove the existence and nonexistence of radial solutions by the variational method with the concentration compactness analysis and the Pohozaev identity.
