摘要:

该文研究如下具有临界增长的分数阶 Kirchhoff 型方程

$ \left(\epsilon^{2s}a+\epsilon^{4s-3}b\int_{\mathbb{R}^{3}}|(-\Delta)^{\frac{s}{2}}u|^{2}{\rm d}x\right) (-\Delta)^{s}u+V(x)u=K(x)f(u)+|u|^{2^{*}_{s}-2}u, \ \ u\in H^{s}(\mathbb{R}^{3}), $

其中 $\epsilon>0$ 为小参数, 常数 $a,b>0$, $s\in(\frac{3}{4},1)$, $2^ {*}_{s}=\frac{6}{3-2s}$ 是临界 Sobolev 指数, 势函数$ V,K:\mathbb{R}^{3}\to\mathbb{R}$ 是非负连续函数, $f:\mathbb{R} \to \mathbb{R}$ 为连续但不可微的次临界非线性项. 作者应用 [Szulkin A, Weth T. Boston: International Press, 2010] 提出的广义 Nehari 流形方法, 证明了基态解的存在性及其集中性质. 此外, 利用 Ljusternik-Schnirelmann 畴数理论, 建立方程解的个数与势函数 $V$ 达到其最小值的集合以及 $K$ 达到其最大值的集合的拓扑之间的关系.

Abstract:

This paper studies the following fractional Kirchhoff-type equation with critical growth

$ \left(\epsilon^{2s}a+\epsilon^{4s-3}b\int_{\mathbb{R}^{3}}|(-\Delta)^{\frac{s}{2}}u|^{2}{\rm d}x\right) (-\Delta)^{s}u+V(x)u=K(x)f(u)+|u|^{2^{*}_{s}-2}u, \ \ u\in H^{s}(\mathbb{R}^{3}), $

where $\epsilon>0$ is a small parameter, $a,b>0$ are constants, $s\in(\frac{3}{4},1)$, $2^{*}_{s}=\frac{6}{3-2s}$ is the Sobolev critical exponent, the potential functions $V,K:\mathbb{R}^{3}\to\mathbb{R}$ are nonnegative continuous functions, and $f:\mathbb{R}\to\mathbb{R}$ is a continuous but non-differentiable subcritical nonlinear term. By using the generalized Nehari manifold method introduced by [Szulkin A, Weth T. Boston: International Press, 2010], the authors prove the existence of ground state solutions and their concentration properties. Furthermore, using Ljusternik-Schnirelmann category theory, they establish a relationship between the number of solutions and the topology of the sets where the potential $V$ attains its minimum and $K$ attains its maximum.

Key words: fractional Kirchhoff equation, critical growth, ground state solution, Ljusternik-Schnirelmann category theory
