Let T be an anisotropic Calderón-Zygmund operator and bLipα,w(Rn,A) with 0<α<1 and Lipα,w(Rn,A) being an anisotropic weighted Lipschitz space. The goal of the paper is to give five boundedness theorems of the commutator [b,T]. Precisely, [b,T] is bounded from Lwq(Rn) to Lw1qrqr(Rn), where wAqr(A), 1/qr=1/qα/n, 1<q<n/α and 1<r<; [b,T] is bounded from Lwq(Rn) to Lw1rr(Rn), when wA1(A) or wAr(A), 1/r=1/qα/n, 1<q<n/α and 1<q<r<; [b,T] is bounded from anisotropic weighted Hardy space Hwp(Rn,A) to Lw1rr(Rn), if wA1(A) or wAr(A), 1/r=1/pα/n and n/(n+α)<p 1<r<; [b,T] is bounded from Hwn/(n+α)(Rn,A) to weak Lebesgue space L1,(Rn) with wA1(A), p=n/(n+α), which are extensions of isotropic settings and new even for the isotropic weighted and anisotropic unweighted settings.

各向异性 Calderón-Zygmund 算子的交换子的加权估计

T为各向异性 Calderón-Zygmund 算子,并且b大号一世pα,w(Rn,一种)0<α<1大号一世pα,w(Rn,一种)是一个各向异性加权 Lipschitz 空间。本文的目标是给出交换子的五个有界定理[b,]. 恰恰,[b,]是有界的大号wq(Rn)大号w1-qrqr(Rn), 在哪里w一种qr(一种),1/qr=1/q-α/n,1<q<n/α1<r<;[b,]是有界的大号wq(Rn)大号w1-rr(Rn), 什么时候w一种1(一种)或者w一种r(一种),1/r=1/q-α/n,1<q<n/α1<q<r<;[b,]以各向异性加权哈代空间为界Hwp(Rn,一种)大号w1-rr(Rn), 如果w一种1(一种)或者w一种r(一种),1/r=1/p-α/nn/(n+α)<p 1<r<;[b,]是有界的Hwn/(n+α)(Rn,一种)到弱勒贝格空间大号1,(Rn)w一种1(一种),p=n/(n+α),它们是各向同性设置的扩展,甚至对于各向同性加权和各向异性未加权设置也是新的。
