一类具有Trudinger-Moser增长的Kirchhoff型椭圆方程组解的存在性和多解性

Existence and multiplicity of solutions to a Kirchhoff type elliptic system with Trudinger-Moser growth

Shengbing Deng, Xingliang Tian

摘要:

研究一类具有Trudinger-Moser指数增长非线性项的Kirchhoff型椭圆方程组解的存在性和多解性。本文首先研究了以下系统\begin{eqnarray*} \left\{ \arraycolsep=1.5pt \begin{array}{ll} -\big(a_1+b_1\|u\|^{2(θ_1-1)}\big)Δu= λH_u(x,u,v)\ \ \ &\ \mbox{in}\ \ \ Ω,\\[2mm] -\big(a_2+b_2\|v\|^{2(θ_2-1)}\big)Δv= λH_v(x,u,v)\ \ \ &\ \mbox{in}\ \ \ Ω,\\[2mm] u=0, v=0\ \ \ \ &\ \mbox{on}\ \ \ \partialΩ, \end{array} \right. \end{eqnarray*}的解的存在性,其中$Ω$是$\mathbb{R}^2$中具有光滑边界的有界区域,当$|s|\rightarrow \infty$对某些$β>0$,$a_1,\ a_2>0$,$b_1,\ b_2> 0$,$θ_1,\ θ_2> 1$和$λ$是正参数时,\ $\|u\|=\big(\int_Ω|\nabla u|^2dx\big)^{1/2}$,$H_u$和$H_v$的行为类似于$e^{β|s|^2}$.在本文的后半部分,我们还讨论了上述系统的一个新的多重性结果,该系统具有一个由非局部依赖引起的正参数。由于Trudinger-Moser嵌入,Kirchhoff项和相关能量泛函缺乏紧致性必须通过一些新技术来克服。

英文摘要:

This paper deals with the existence and multiplicity of solutions for a class of Kirchhoff type elliptic system involving the Trudinger-Moser exponential growth nonlinearities. We first study the existence of solutions for the following system \begin{eqnarray*} \left\{ \arraycolsep=1.5pt \begin{array}{ll} -\big(a_1+b_1\|u\|^{2(θ_1-1)}\big)Δu= λH_u(x,u,v)\ \ \ &\ \mbox{in}\ \ \ Ω,\\[2mm] -\big(a_2+b_2\|v\|^{2(θ_2-1)}\big)Δv= λH_v(x,u,v)\ \ \ &\ \mbox{in}\ \ \ Ω,\\[2mm] u=0, v=0\ \ \ \ &\ \mbox{on}\ \ \ \partialΩ, \end{array} \right. \end{eqnarray*} where $Ω$ is a bounded domain in $\mathbb{R}^2$ with smooth boundary,\ $\|u\|=\big(\int_Ω|\nabla u|^2dx\big)^{1/2}$, $H_u$ and $H_v$ behave like $e^{β|s|^2}$ when $|s|\rightarrow \infty$ for some $β>0$, $a_1,\ a_2>0$, $b_1,\ b_2> 0$, $θ_1,\ θ_2> 1$ and $λ$ is a positive parameter. In the later part of the paper, we also discuss a new multiplicity result for the above system with a positive parameter induced by the nonlocal dependence. The Kirchhoff term and the lack of compactness of the associated energy functional due to the Trudinger-Moser embedding have to be overcome via some new techniques.
