Multiple nodal solutions of nonlinear Choquard equations

Zhihua Huang, Jianfu Yang, Weilin Yu

摘要:

本文研究了非线性Choquard方程\begin{equation*} \ \ \ \ (P)\ \ \ \ \begin{cases} -Δu+u=(|x|^{-1}\ast|u|^p)|u|^{p-2}u \ \ \ \text{in}\ \mathbb{R}^3, \ \ \ \ \\ u\in H^1(\mathbb{R}^3),\\ \end{cases} \end{equation*}的多节点解的存在性,其中$p\in (\frac{5}{2},5)$ .我们证明了对于任何正整数$k$,问题$(P)$至少有一个径向对称的解决方案改变符号正好$k$倍。

英文摘要:

In this paper, we consider the existence of multiple nodal solutions of the nonlinear Choquard equation \begin{equation*} \ \ \ \ (P)\ \ \ \ \begin{cases} -Δu+u=(|x|^{-1}\ast|u|^p)|u|^{p-2}u \ \ \ \text{in}\ \mathbb{R}^3, \ \ \ \ \\ u\in H^1(\mathbb{R}^3),\\ \end{cases} \end{equation*} where $p\in (\frac{5}{2},5)$. We show that for any positive integer $k$, problem $(P)$ has at least a radially symmetrical solution changing sign exactly $k$-times.
