摘要:
给出了一个关于权函数满足的充分条件,该条件使得加权Hardy算子与中心BMO函数生成的交换子在Herz型空间中有界。进一步地,将所得结论推广到了k阶的情形。
Abstract: In this paper, we present sufficient conditions on weighted function which ensures the boundedness of commutators generated by weighted Hardy operators and central BMO functions on Herz spaces and Morrey-Herz spaces, respectively. Moreover, the corresponding results are extended to the case of k-th order.
