Hamilton椭圆型方程组最小能量节点解的存在性和对称性

Existence and symmetry of least energy nodal solutions for Hamiltonian elliptic systems

Denis Bonheure, Ederson Moreira dos Santos, Miguel Ramos, Hugo Tavares

摘要:

本文证明了带Hénon-type权的Hamilton椭圆型方程组\[ -Δu = |x|^β |v|^{q-1}v, \quad -Δv =|x|^α|u|^{p-1}u\quad { in } Ω, \qquad u=v=0 { on } \partial Ω, \]最小能量节点解的存在性,其中$Ω$是$\mathbb{R}^N$,$N\geq 1$,$α, β\geq 0$中的有界光滑区域,非线性项是超线性和次临界的,即\[ 1> \frac{1}{p+1}+\frac{1}{q+1}> \frac{N-2}{N}. \]当$Ω$是以原点为中心的球或环,$N \geq 2$,我们表明,这些解决方案显示所谓的叶状Schwarz对称。人们很自然地猜想这些解不是径向对称的。我们提供了这样一个对称性破缺的参数范围内的解决方案的系统表现得像一个单一的方程的解决方案。我们对上述系统的结果是新的,即使在Lane-Emden系统的情况下(即没有重量)。据我们所知,这是第一篇关于强耦合椭圆型方程组的最小能量节点解及其对称性的结果。

英文摘要:

In this paper we prove existence of least energy nodal solutions for the Hamiltonian elliptic system with Hénon-type weights \[ -Δu = |x|^β |v|^{q-1}v, \quad -Δv =|x|^α|u|^{p-1}u\quad { in } Ω, \qquad u=v=0 { on } \partial Ω, \] where $Ω$ is a bounded smooth domain in $\mathbb{R}^N$, $N\geq 1$, $α, β\geq 0$ and the nonlinearities are superlinear and subcritical, namely \[ 1> \frac{1}{p+1}+\frac{1}{q+1}> \frac{N-2}{N}. \] When $Ω$ is either a ball or an annulus centred at the origin and $N \geq 2$, we show that these solutions display the so-called foliated Schwarz symmetry. It is natural to conjecture that these solutions are not radially symmetric. We provide such a symmetry breaking in a range of parameters where the solutions of the system behave like the solutions of a single equation. Our results on the above system are new even in the case of the Lane-Emden system (i.e. without weights). As far as we know, this is the first paper that contains results about least energy nodal solutions for strongly coupled elliptic systems and their symmetry properties.
