关于Herz型空间中的分数次积分算子的Hardy-Littlewood-Sobolev定理

On the Hardy-Littlewood-Sobolev Theorem of the Fractional Integration on Herz-type Spaces

研究了Herz型空间中的分数次积分算子的弱型估计，与[2]一起完整地建立了Herz型空间中的分数次积分算子的Hardy－Littlewood-Soboev定理．

In this paper, we discussed the weak estimates of fractional integration on Herz - type spaces, and established the Hardy - Littlewood - Sobolev theorems of fractional integration on Herz - type spaces completely together with[2].
