Existence and concentration of semi-classical ground state solutions for Chern-Simons-Schr\"{o}dinger system
首发时间:2021-01-12
Abstract:In this paper, we study the equation\begin{equation*} -\varepsilon^{2}\Delta u+ V(x)u+\left(A_{0}(u)+A_{1}^{2}(u)+A_{2}^{2}(u)\right)u=f(u) \ \ \ \ \mathrm{in} ~ H^{1}(\mathbb{R}^{2}),\end{equation*}where $\varepsilon$ is a small parameter, $V$ is the external potential,$A_i(i=0,1,2)$ is the gauge field and $f\in C(\mathbb{R}, \mathbb{R})$ is 5-superlinear growth.By using variational methods and analytic technique, we prove that this system possesses a ground state solution $u_\varepsilon$.Moreover, our results show that, as $\varepsilon\to 0$, the global maximum point $x_\varepsilon$ of $u_\varepsilon$ must concentrate at the global minimum point $x_0$ of $V$.

Chern-Simons-Schr\"{o}dinger 系统的半经典基态解的存在性和集中性
摘要:本文在$H^{1}(\mathbb{R}^{2})$中研究方程$-\varepsilon^{2}\Delta u+ V(x)u+\left(A_{0}(u)+A_{1}^{2}(u)+A_{2}^{2}(u)\right)u=f(u)$, 其中$\varepsilon$是小参数,$V$是外部位势,$A_i(i=0,1,2)$是规范场并且$f\in C(\mathbb{R}, \mathbb{R})$ 满足超5次线性增长。利用变分法和分析技巧,我们证明了该系统有一个基态解$u_\varepsilon$。此外,结果还表明,当$\varepsilon\to 0$ 时,$u_\varepsilon$的全局极大值点$x_\varepsilon$ 一定集中在$V$的全局极小值点$x_0$处。
