摘要
本文研究了具有非光滑核的奇异积分算子Tf(x)=∫_(R^n)K(x,y)f(y)dy与加权Lipschtiz函数b生成的交换子[b,T]的Sharp极大函数的点态估计,并应用该估计证明了这类交换子[b,T]是由L^p(v)到L^q(v^(1-q))的有界算子,其中b∈Lip_(β,v),v ∈ A_1,1/q=1/p-β/n,0<β<1,1<p<q<∞,改进了一些已知结果。
This paper is concerned with the pointwise estimates for the sharp maximal function of the commutator [b,T]generated by the singular integral operator T with non-smooth kernelsTf(x) = ∫RnK(x,y)f(y)dyand a Lipβ,vfunction b ,it is shown that the commutator [b,T] is bounded from Lp(v) to Lq(v1 -q) ,where b∈Lipβ,v,v∈A1,1q=1p-βn,0 〈 β 〈 1,1 〈 p 〈 q 〈 ∞, some known results are improved.
