AI总结:

研究含线性扰动的临界哈密顿椭圆系统,在适当条件下,通过特定构造方法得到无穷多个变号解,这些解由正径向解和负泡组成,能量可任意大。

摘要:

本文研究如下椭圆系统:\(\begin{cases}-\Delta u = |v|^{p - 1}v+\epsilon(\alpha u+\beta_1v),&\text{在 }\Omega 中\\-\Delta v = |u|^{q - 1}u+\epsilon(\beta_2u+\alpha v),&\text{在 }\Omega 中\u = v = 0,&\text{在 }\partial\Omega 上\end{cases}\),其中\(\Omega\)是\(\mathbb{R}^N\)中的单位球,\(\epsilon\)是小参数等。在适当假设及对\((p,q)\)和\(N\)的限制下,构造出无穷多个变号解,其形如一个正径向解加上在合适半径正多边形上排列的\(k\)个负泡,能量可任意大。

英文摘要:

In this paper, we study the following elliptic system \begin{equation}\label{main_1} \begin{cases} -Δu = |v|^{p-1} v + ε(αu + β_1 v), & \text{in } Ω, \\ -Δv = |u|^{q-1} u + ε(β_2 u + αv), & \text{in } Ω, \\ u = v = 0, & \text{on } \partial Ω, \end{cases} \tag{*} \end{equation} where \(Ω\) is the unit ball in $\mathbb{R}^N$, \(ε\) is a small parameter, \(α\), \(β_1\) and \(β_2\) are real numbers, \((p, q)\) is a pair of positive numbers lying on the critical hyperbola \begin{equation} \frac{1}{p+1} + \frac{1}{q+1} = \frac{N-2}{N}.\nonumber \end{equation} Under suitable assumptions and suitable restrictions on $(p,q)$ and $N$, we construct infinitely many sign-changing solutions to \eqref{main_1} which look like a positive radial solution to \eqref{main_1} crowned by $k$ negative bubbles arranged on a regular polygon of a suitable radius, whose energy can be arbitrarily large.
