Hiroki Saito, Hitoshi Tanaka, Toshikazu Watanabe

摘要:

令$n\ge 2$为空间维度。本文的目的是得到加权Choquet-Lorentz空间$L^{p,q}(H_{w}^{d})$上$α$阶的分数极大算子${\mathfrak M}α$,$0\leα<n$的加权估计,其中权$w$是任意的,基本测度是加权$d$维Hausdorff容度$H^{d}_{w}$,$0<d\le n$ .考虑两个参数$α$和$d$的依赖性,建立了${\mathfrak M}_α$的Festimman-Stein型不等式的一般形式.我们的结果包含了Adams,\cite{Ad}和Orobitg,Verdera \cite{OV}的工作作为特例.我们的结果也意味着唐结果\cite{Ta},如果我们假设的重量$w$是在Muckenhoupt $A_{1}$类。

英文摘要:

Let $n\ge 2$ be the spatial dimension. The purpose of this note is to obtain some weighted estimates for the fractional maximal operator ${\mathfrak M}α$ of order $α$, $0\leα<n$, on the weighted Choquet-Lorentz space $L^{p,q}(H_{w}^{d})$, where the weight $w$ is arbitrary and the underlying measure is the weighted $d$-dimensional Hausdorff content $H^{d}_{w}$, $0<d\le n$. Concerning a dependence of two parameters $α$ and $d$, we establish a general form of the Fefferman-Stein type inequalities for ${\mathfrak M}_α$. Our results contain the works of Adams, \cite{Ad} and of Orobitg and Verdera \cite{OV} as the special cases. Our results also imply the Tang result \cite{Ta}, if we assume the weight $w$ is in the Muckenhoupt $A_{1}$-class.
