摘要
在本文中,我们主要关注研究如下带 Hardy 势的分数阶非线性薛定谔-Korteweg-De Vries(简称 NLS-KdV)方程组的束缚态与基态解的存在性:\begin{equation*} \left\{ \begin{aligned} (-\Delta)^{s_{1}} u - \lambda_{1} \frac{u}{|x|^{2s_{1}}} - u^{2_{s_{1}}^{*}-1} &= 2\nu h(x) u^{}v^{} & \quad \mbox{in} ~ \mathbb{R}^{N}, (-\Delta)^{s_{2}} v - \lambda_{2} \frac{v}{|x|^{2s_{2}}} - v^{2_{s_{2}}^{*}-1} &= \nu h(x) u^{2} & \quad \mbox{in} ~ \mathbb{R}^{N}, u,v >0 \quad \mbox{in} ~ \mathbb{R}^{N} \setminus \{0\}, \end{aligned} \right. \end{equation*} 其中 且 。通过对参数 与函数 施加特定假设,我们利用集中紧致原理与山路定理得到基态解。
