研究了粗糙核分数次积分及交换子在Herz型Hardy空间上的加权估计。当Ω∈Ls(Sn-1)(1<s<∞)时,利用原子分解证明了粗糙核分数次积分TΩ,l以及由它和BM痹O函数生成的交换子[ b,TΩ,l ]是从加权Herz型Hardy空间到(弱)加权Herz空间上有界的。同时,对粗糙核分数次极大算子也得到了相应的结果。
The main goal of this paper is to study the weighted estimates about the fractional integrals with rough kernels and its commutators on the Herz-type Hardy spaces.AsΩ∈Ls(Sn-1)(1〈s〈∞), it is proved that the fractional inte-grals TΩ,l and its commutators [ b,TΩ,l ] generated by the BMO functions are bounded from the weighted Herz-type Har-dy spaces to the weighted Herz spaces by using the atomic decompositions.Also, the corresponding results are also obtained for the maximal fractional integrals with rough kernels.
