一般分数次积分算子的算子在加权Morrey空间上有界的充要条件

Necessary and sufficient conditions for boundedness of commutators of the general fractional integral operators on weighted Morrey spaces

Zengyan Si, Fayou Zhao

摘要:

本文证明了$b$在$Lip_{\bz}(\bz)$中当且仅当$b$与一般分数次积分算子$L^{-α/2}$相乘的交换子$[b,L^{-α/2}]$从加权Morrey空间$L^{p,k}(ω)$到$L^{q,kq/p}(ω^{1-(1-α/n)q},ω)$有界,其中$0<β<1$,$0<α+β<n, 1<p<{n}/({α+β})$,${1}/{q}={1}/{p}-{(α+β)}/{n},$ $0\leq k<{p}/{q},$ $ω^{{q}/{p}}\in A_1$和$ r_ω> \frac{1-k}{p/q-k},$,这里$r_ω$表示$ω$在逆Hölder条件下的临界指标.

英文摘要:

We prove that $b$ is in $Lip_{\bz}(\bz)$ if and only if the commutator $[b,L^{-α/2}]$ of the multiplication operator by $b$ and the general fractional integral operator $L^{-α/2}$ is bounded from the weighed Morrey space $L^{p,k}(ω)$ to $L^{q,kq/p}(ω^{1-(1-α/n)q},ω)$, where $0<β<1$, $0<α+β<n, 1<p<{n}/({α+β})$, ${1}/{q}={1}/{p}-{(α+β)}/{n},$ $0\leq k<{p}/{q},$ $ω^{{q}/{p}}\in A_1$ and $ r_ω> \frac{1-k}{p/q-k},$ and here $r_ω$ denotes the critical index of $ω$ for the reverse Hölder condition.
