Claudianor O. Alves, Youjun Wang, Yaotian Shen

摘要:

利用变分方法结合扰动变分方法,研究了拟线性薛定谔方程\begin{equation*}\label{1.1} -Δu+ V(x)u+ \fracκ{2}[Δ|u|^2]u=l(u),\ x\in\mathbb{R}^N, \end{equation*}非平凡经典解的存在性,其中$V:\mathbb{R}^N\rightarrow \mathbb{R}$和$l:\mathbb{R} \to \mathbb{R}$是连续函数,$κ$是参数,$N\geq 3$ .该模型已在等离子体物理和非线性光学中提出。作为一个主要的新颖性与以前的一些结果,我们能够处理的情况下$κ>0$。

英文摘要:

Using variational methods combined with perturbation arguments, we study the existence of nontrivial classical solution for the quasilinear Schrödinger equation \begin{equation*}\label{1.1} -Δu+ V(x)u+ \fracκ{2}[Δ|u|^2]u=l(u),\ x\in\mathbb{R}^N, \end{equation*} where $V:\mathbb{R}^N\rightarrow \mathbb{R}$ and $l:\mathbb{R} \to \mathbb{R}$ are continuous function, $κ$ is a parameter and $N\geq 3$. This model has been proposed in plasma physics and nonlinear optics. As a main novelty with respect to some previous results, we are able to deal with the case $κ>0$.
