摘要
利用Littlewood-Paley分解及权估计,在Triebel-Lizorkin空间上得到了一类奇异积分算子在Tf（x）=＋∞∑j=-∞ Kj＊f（x））的有界性.作为应用,对粗糙核奇异积分算子TΩf（x）=p.v.∫R″（Ω（y）/ρ（y）^β）f（x-y）dy,也得到了相应的结果,从而推广了已有结果.
It is well-known that the Triebel-Lizorkin space F·α,qp（Rn） is a unified setting of many well-known function spaces including Lebesgue spaces Lp（Rn）,the Hardy spaces Hp（Rn） and the Sobolev spaces Lαp（Rn）.So it is very meaningful to study the boundedness on Triebel-Lizorkin spaces for sigular integral operators.For a class of sigular integral operators defined by Tf（x）=＋∞∑j=-∞ Kj＊f（x）,the boundedness on Triebel-Lizorkin spaces are obtained by using the Littlewood-Paley decomposition and the estimates of weight.As a application,for the rough kernel singular integral defined by TΩf（x）=p.v.∫R″（Ω（y）/ρ（y）^β）f（x-y）dydy.the corresponding result is also obtained.Therefore,the known result are extended.
