$\mathbb{R}^{4}$中具有临界增长的两分量椭圆型方程组的驻波:吸引情形

Standing waves for two-component elliptic system with critical growth in $\mathbb{R}^{4}$: the attractive case

Lun Guo, Qi Li, Xiao Luo, Riccardo Molle

摘要:

本文考虑具有临界增长的二分量椭圆型方程组\begin{equation*} \begin{cases} -Δu+(V_1(x)+λ)u=μ_1u^{3}+βuv^{2}, \ \ x\in \mathbb{R}^4, -Δv+(V_2(x)+λ)v=μ_2v^{3}+βvu^{2}, \ \ x\in \mathbb{R}^4 , % u\geq 0, \ \ v\geq 0 \ \text{in} \ \R^4. \end{cases} \end{equation*},其中$V_j(x) \in L^{2}(\mathbb{R}^4)$是非负势,非线性系数$β,μ_j$,$j=1,2$为正.这里我们还假设为$λ>0$。在$β>\max\{μ_1,μ_2\}$的假设下,利用变分方法和度理论,证明了方程正解的存在性和多解性。这些结果推广了Cerami和Passaseo关于半空间上半线性薛定谔方程的结果(SIAM J. Math. Anal.,28,867-885,(1997))的存在性,同时将Liu和Liu(Calc.变种偏微分方程,59:145,(2020))。

英文摘要:

In this paper, we consider the following two-component elliptic system with critical growth \begin{equation*} \begin{cases} -Δu+(V_1(x)+λ)u=μ_1u^{3}+βuv^{2}, \ \ x\in \mathbb{R}^4, -Δv+(V_2(x)+λ)v=μ_2v^{3}+βvu^{2}, \ \ x\in \mathbb{R}^4 , % u\geq 0, \ \ v\geq 0 \ \text{in} \ \R^4. \end{cases} \end{equation*} where $V_j(x) \in L^{2}(\mathbb{R}^4)$ are nonnegative potentials and the nonlinear coefficients $β,μ_j$, $j=1,2$, are positive. Here we also assume $λ>0$. By variational methods combined with degree theory, we prove some results about the existence and multiplicity of positive solutions under the hypothesis $β>\max\{μ_1,μ_2\}$. These results generalize the results for semilinear Schrödinger equation on half space by Cerami and Passaseo (SIAM J. Math. Anal., 28, 867-885, (1997)) to the above elliptic system, while extending the existence result from Liu and Liu (Calc. Var. Partial Differential Equations, 59:145, (2020)).
