摘要
利用核函数估计方法研究了具有H(m)-型核函数的奇异积分算子和加权Lipschitz函数生成的交换子的性质.通过建立该交换子的sharp极大函数的点态估计,证明了上述交换子是Lp(μ)到Lp(μ1 q)上的有界算子,推广了一些已有的结果.
The properties of commutators generated by the singular integral with H(m)-kernel and the weighted Lipschitz function are studied by the kernel function estimation. By the methods of eastablishing a pointwise estimate of sharp maximal function for those commutators, it is proved that above commutator is bounded form LP(μ) to Lp(μ1-q), which improves some existing results.
