一个Paneitz型问题的变号鼓泡塔解

Sign-changing bubble tower solutions for a Paneitz-type problem

Wenjing Chen, Xiaomeng Huang

摘要:

本文考虑如下双调和问题\begin{equation}\label{ineq} \begin{cases} Δ^2 u=|u|^{\frac{8}{N-4}}u &\text{ in } \ Ω\backslash \overline{B(ξ_0,\varepsilon)}, u=Δu=0 &\text{ on } \ \partial (Ω\backslash \overline{B(ξ_0,\varepsilon)}), \end{cases} \end{equation}其中$Ω$是$\mathbb{R}^N$,$N\geq 5$中的开有界区域,$B(ξ_0,\varepsilon)$是以$ξ_0$为中心的球,半径为$\varepsilon$,$\varepsilon$是一个小的正参数.我们得到了问题(\ref{ineq})解的存在性,这是一个任意大数目的符号变化的解决方案,其轮廓是一个叠加的气泡交替符号集中在中心的孔。

英文摘要:

This paper is concerned with the following biharmonic problem \begin{equation}\label{ineq} \begin{cases} Δ^2 u=|u|^{\frac{8}{N-4}}u &\text{ in } \ Ω\backslash \overline{B(ξ_0,\varepsilon)}, u=Δu=0 &\text{ on } \ \partial (Ω\backslash \overline{B(ξ_0,\varepsilon)}), \end{cases} \end{equation} where $Ω$ is an open bounded domain in $\mathbb{R}^N$, $N\geq 5$, and $B(ξ_0,\varepsilon)$ is a ball centered at $ξ_0$ with radius $\varepsilon$, $\varepsilon$ is a small positive parameter. We obtain the existence of solutions for problem (\ref{ineq}), which is an arbitrary large number of sign-changing solutions whose profile is a superposition of bubbles with alternate sign which concentrate at the center of the hole.
