整环上一般$L^{p}$函数的分式极大函数的弱可微性

Weak differentiability for fractional maximal functions of general $L^{p}$ functions on domains

João P. G. Ramos, Olli Saari, Julian Weigt

摘要:

设$Ω\subset \mathbb{R}^{n}$是有界域.证明了在一定的结构假设下,当光滑性指数$α\geq 1$满足一定条件时,对于所有的$p > 1$,相对于$Ω$的分数极大算子映射$L^{p}(Ω) \to W^{1,p}(Ω)$.特别是,结果在以前未知的$p \in (1, n/(n-1)]$范围内有效。作为应用,我们证明了一个端点正则性结果。

英文摘要:

Let $Ω\subset \mathbb{R}^{n}$ be bounded a domain. We prove under certain structural assumptions that the fractional maximal operator relative to $Ω$ maps $L^{p}(Ω) \to W^{1,p}(Ω)$ for all $p > 1$, when the smoothness index $α\geq 1$. In particular, the results are valid in the range $p \in (1, n/(n-1)]$ that was previously unknown. As an application, we prove an endpoint regularity result in the domain setting.
