摘要/Abstract

摘要：

该文研究如下一类非线性Choquard方程 $\begin{equation} -\Delta u + V(x)u= (I_{\alpha}* F(u))f(u), \hskip0.5cm x\in{{\Bbb R}} ^{N}, \end{equation}$ 其中 $N \geq 3$ ， $\alpha \in (0, N)$ ， $I_{\alpha}$ 是Riesz势, 位势函数 $V:\mathbb{R} ^{N} \rightarrow \mathbb{R}$ 为连续函数， $F\in {\cal C}^{1}(\mathbb{R}，\mathbb{R})$ , 且 $F'(s)=f(s)$ . 在函数 $V$ 和 $f$ 满足合适的条件下(但 $f$ 不必满足(AR)条件), 利用变分方法，该文证明了上述方程存在一个正的基态解.

Abstract:

In this paper we study the following nonlinear Choquard equation $\begin{equation} -\Delta u + V(x)u= (I_{\alpha}* F(u))f(u), \hskip0.5cm x\in{{\Bbb R}} ^{N} ,\end{equation}$ where $N \geq 3$ , $\alpha \in (0, N)$ , $I_{\alpha}$ is the Riesz potential, $V(x):\mathbb{R} ^{N} \rightarrow \mathbb{R}$ is a given potential function, and $F\in {\cal C}^{1}(\mathbb{R}, \mathbb{R})$ with $F'(s)=f(s)$ . Under assumptions on $V$ and $f$ , we do not require the $(AR)$ condition of $f$ , the existence of ground state solutions are obtained via variational methods.
