摘要:

该文研究如下一类非线性Choquard方程 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$$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 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.

Key words: Choquard equation, Ground state solution, Variational methods
