具有分数阶扩散的确定性KPZ方程:定态问题

Towards a deterministic KPZ equation with fractional diffusion: The stationary problem

Boumediene Abdellaoui, Ireneo Peral

摘要:

本文研究了分数阶拟线性问题\begin{equation*} \left\{ \begin{array}{rcll} (-Δ)^s u &= & |\nabla u|^{p}+ łf & \text{ in }Ω, u &=& 0 &\hbox{ in } \mathbb{R}^N\setminusΩ, u&>&0 &\hbox{ in }Ω, \end{array}% \right. \end{equation*} %解的存在性,其中$Ω\subset \ren$是有界正则区域($\mathcal{C}^2$是充分的),$s\in (\frac 12, 1)$,$1<p$和$f$是可测非负函数,并作了适当的假设.在三种情况下分别进行分析,亚临界$1<p<2s$、临界$p=2s$和超临界$p>2s$。

英文摘要:

In this work we analyze the existence of solution to the fractional quasilinear problem, \begin{equation*} \left\{ \begin{array}{rcll} (-Δ)^s u &= & |\nabla u|^{p}+ łf & \text{ in }Ω, u &=& 0 &\hbox{ in } \mathbb{R}^N\setminusΩ, u&>&0 &\hbox{ in }Ω, \end{array}% \right. \end{equation*}% where $Ω\subset \ren$ is a bounded regular domain ($\mathcal{C}^2$ is sufficient), $s\in (\frac 12, 1)$, $1<p$ and $f$ is a measurable nonnegative function with suitable hypotheses. The analysis is done separately in three cases, subcritical, $1<p<2s$, critical, $p=2s$, and supercritical, $p>2s$.
