A weighted fractional problem involving a singular nonlinearity and a $L^1$ data

Akasmika Panda, Debajyoti Choudhuri, Leandro S. Tavares

摘要:

在这篇文章中,我们证明了以下问题的唯一熵解的存在性:\begin{equation} \begin{split} (-Δ)_{p,α}^su&= f(x)h(u)+g(x) ~\text{in}~Ω,\\ u&>0~\text{in}~Ω,\\ u&= 0~\text{in}~\mathbb{R}^N\setminusΩ,\nonumber \end{split} \end{equation}其中域$Ω\subset \mathbb{R}^N$是有界的,并包含原点,$ α\in[0,\frac{N-ps}{2})$,$s\in (0,1)$,$2-\frac{s}{N}<p<\infty$,$sp<N$,$g\in L^1(Ω)$,$f\in L^q(Ω)$对于$q>1$和$h$是一个一般奇异函数,奇异性为0。此外,具有权重$α$的分数$p$-Laplacian由下式给出:$$(-Δ)_{p,α}^su(x)=\text{P. V.}\int_{\mathbb{R}^N}\frac{|u(x)-u(y)|^{p-2}(u(x)-u(y))}{|x-y|^{N+ps}}\frac{dy}{|x|^α|y|^α},~\forall x\in \mathbb{R}^N.$$

英文摘要:

In this article, we show the existence of a unique entropy solution to the following problem: \begin{equation} \begin{split} (-Δ)_{p,α}^su&= f(x)h(u)+g(x) ~\text{in}~Ω,\\ u&>0~\text{in}~Ω,\\ u&= 0~\text{in}~\mathbb{R}^N\setminusΩ,\nonumber \end{split} \end{equation} where the domain $Ω\subset \mathbb{R}^N$ is bounded and contains the origin, $ α\in[0,\frac{N-ps}{2})$, $s\in (0,1)$, $2-\frac{s}{N}<p<\infty$, $sp<N$, $g\in L^1(Ω)$, $f\in L^q(Ω)$ for $q>1$ and $h$ is a general singular function with singularity at 0. Further, the fractional $p$-Laplacian with weight $α$ is given by $$(-Δ)_{p,α}^su(x)=\text{P. V.}\int_{\mathbb{R}^N}\frac{|u(x)-u(y)|^{p-2}(u(x)-u(y))}{|x-y|^{N+ps}}\frac{dy}{|x|^α|y|^α},~\forall x\in \mathbb{R}^N.$$
