摘要：

该文主要讨论一般非线性项情形下一类分数阶Kirchhoff型约束变分问题在空间$H^s(\mathbb{R}^N)$上极小解的存在性和Schwarz对称性.利用单调递减重排不等式和伸缩技巧, 当非线性项满足合适的条件时, 该文细致的讨论了相应约束变分问题在空间$H^s(\mathbb{R}^N)$上极小解的存在性与非线性项的指数和约束$\int_{\mathbb{R}^N}|u|^2{\rm d}x=c^2$中参数$c$的关系.

关键词: 约束变分, 极小解, 分数阶Kirchhoff问题, Schwarz对称

Abstract:

In this paper, the existence and Schwarz symmetry of minimizers for a fractional Kirchhoff constrained variational problem with general nonlinear term were studied in space $H^s(\mathbb{R} ^N)$. Using symmetric decreasing rearrangement inequality and scaling technique, the relation between existence of minimizers for a fractional Kirchhoff constrained variational problem with the exponent of nonlinear term and parameter $c$ in $\int_{\mathbb{R} ^N}|u|^2{\rm d}x=c^2$ was discussed.

Key words: Constrained variational, Minimizer, Fractional Kirchhoff problem, Schwarz symmetric
