摘要:

本文证明了以下含奇性的非局部椭圆型偏微分方程\begin{align} (-Δ)_{p(\cdot)}^{s} u&=\fracλ{|u|^{γ(x)-1}u}+f(x,u)~\text{in}~Ω,\nonumber u&=0~\text{in}~\mathbb{R}^N\setminusΩ,\nonumber \end{align}无穷多个非负解的存在性,其中$Ω\subset\mathbb{R}^N,\, N\geq2$是光滑的有界区域,$λ>0$,$s\in (0,1)$,$γ(x)\in(0,1)$对所有$x\in\barΩ$,$N>sp(x,y)$对所有$(x,y)\in\barΩ\times\barΩ$,$(-Δ)_{p(\cdot)}^{s}$是变指数的分数阶$p(\cdot)$-Laplacian算子.非线性函数$f$满足一定的增长条件。利用Moser迭代技术建立了解的一致$L^{\infty}(\barΩ)$估计.

英文摘要:

We prove the existence of infinitely many nonnegative solutions to the following nonlocal elliptic partial differential equation involving singularities \begin{align} (-Δ)_{p(\cdot)}^{s} u&=\fracλ{|u|^{γ(x)-1}u}+f(x,u)~\text{in}~Ω,\nonumber u&=0~\text{in}~\mathbb{R}^N\setminusΩ,\nonumber \end{align} where $Ω\subset\mathbb{R}^N,\, N\geq2$ is a smooth, bounded domain, $λ>0$, $s\in (0,1)$, $γ(x)\in(0,1)$ for all $x\in\barΩ$, $N>sp(x,y)$ for all $(x,y)\in\barΩ\times\barΩ$ and $(-Δ)_{p(\cdot)}^{s}$ is the fractional $p(\cdot)$-Laplacian operator with variable exponent. The nonlinear function $f$ satisfies certain growth conditions. Moreover, we establish a uniform $L^{\infty}(\barΩ)$ estimate of the solution(s) by the Moser iteration technique.
