一类带半(θ,N)核算子的交换子在Hardy型空间上的弱型估计

The weak estimates of commutators generated by a class of operators with semi-(θ,N)kernel on Hardy-type spaces

设[b ,T] 表示由函数 b∈Lipβ(Rn) 与带半(θ ,N) 核算子 T 生成的交换子 ,研究了 [b ,T] 从Hardy空间到弱Lebesgue空间和从Herz型Hardy空间到弱Herz空间上的有界性 .

Assume that is commutator generated by function b∈Lip β(R n) and operator T with semi- (θ,N) kernel. In this Paper the authors discuss the boundedness of from Hardy spaces to weak Lebesgue spaces and from Herz type Hardy spaces to weak Herz spaces.
