摘要:

研究如下的三维Kirchhoff型问题
其中,ΩR3中具有光滑边界的有界区域,0∈Ω, 0 < q < 1, 0 ≤ s < 1, 4 < p < 2*(s)=2(3-s), a,b,λ > 0. 运用变分方法,证明当λ > 0足够小时,这一方程至少有2个正解.

关键词: Kirchhoff型问题, Hardy项, Nehari流形, 正解

Abstract:

We investigate the following three-dimensional Kirchhoff-type problem
where Ω is a smooth bounded domain in R3, 0∈Ω, 0 < q < 1, 0 ≤ s < 1, 4 < p < 2*(s)=2(3-s), parameters a,b,λ > 0. We have established the existence of multiple positive solutions to the problem by using variational methods.

Key words: Kirchhoff-type problem, Hardy term, Nehari manifold, positive solutions
