$0<p<\infty$的加权估计

Weighted estimates of commutators for $0<p<\infty$

Shunchao Long

摘要:

对所有的$0<p<\infty$,我们建立了次线性算子的$BMO$算子的加权不等式.对于权$w$满足$q$阶与$0<q<p$阶的加倍条件和逆Hölder条件,我们证明了在$L^p$上有界的$\bullet$算子$T_b$,对于所有的$1<p<\infty$,从$L^p_w$的某些子空间到$L^p_w$和到其自身是有界的,这些结果也适用于奇异积分算子和Hardy-Littelwood极大算子的算子,et.al,不能从$H^1$到$L^1$有界,并且其估计对于足够小的$0<p$是开放问题; $\bullet$交换子$T_b$,其相关算子$T$在$L^p$上与$1<p<\infty$有界,对于所有$0<p<\infty$,从$L^p_w$的某些子空间到$L^p_w$以及从$L^p_w$的某些子空间到其他子空间都有界,这些方法应用于极大算子如奇异积分极大算子、Carleson算子和多项式Carleson算子等的估计,这些估计对于每一个$0<p<\infty$都是公开问题;特别是$\bullet$,这意味着上面的算子从$H^p_w$到$L^p_w$以及对于所有$0<p\leq 1$到其自身是有界的。

英文摘要:

We establish weighted inequalities for $BMO$ commutators of sublinear operators for all $0<p<\infty$. For weights $w$ satisfying the doubling condition of order $q$ with $0<q<p$ and the reverse Hölder condition, we prove that $\bullet$ commutators $T_b$, which are bounded on $L^p$ with $1<p<\infty$, are bounded from some subspaces of $L^p_w$ to $L^p_w$ and to themselves for all $0<p<\infty$, these are applied to the commutators of singular integral operators and Hardy-Littelwood maximal operator, et.al, which are known to fail to be bounded from $H^1$ to $L^1$ and whose estimate has been open problems for $0<p$ enough small; $\bullet$ commutators $T_b$, whose associated operators $T$ are bounded on $L^p$ with $1<p<\infty$, are bounded from some subspaces of $L^p_w$ to $L^p_w$ and from some subspaces of $L^p_w$ to others for all $0<p<\infty$, these are applied to the commutators of maximal operators such as singular integral maximal operators, Carleson operator and the polynomial Carleson operator, et.al, the estimate of these commutators has been open problems for each $0<p<\infty$; $\bullet$ in particular, these imply that the commutators above are bounded from $H^p_w$ to $L^p_w$ and to itself for all $0<p\leq 1$.
