摘要
研究截口上的奇异积分高阶交换子Hbmf(x),利用截口F关于核的ki(x,y)估计,在一定假设下得到了Hbm的Sharp极大函数估计和加权弱(1,1)型估计.
The aim of this paper is to study the weighted estimates for the higher order commutators of singular integral operatorsH^mbf(x). Under some hypotheses of ki(x,y) associated with the sections F, the sharp maximal functions and the weighted weak-type (1,1) estimates for H^mbf is obtained.
