证明了带变量核的Marcinkiewicz积分交换子μΩ,b在加权弱Hardy空间上的有界性。利用加权弱Hardy空间上的原子分解理论,得到了核函数满足一定条件下μΩ,b的有界性结论,这里b∈BMO。同时,得到了与参数型的Marcinkiewicz积分交换子μρΩ,b类似的结果。
The boundedness of the commutators μΩ,b related to Marcinkiewicz with variable kernels on weighted weak Hardy spaces are proved. By the atomic decompositions of weighted weak Hardy spaces, some results about μΩ,b are obtained under the hypothesis that the kernel satisfies a certain condition, where b∈BMO. The same results are shown for the commutator μρΩ,b related to the parametric Marcinkiewicz integral μρΩ.
