一类分数次积分算子在Herz型Hardy空间上的有界性

Boundedness of some sublinear operators on Herz-type Hardy spaces

通过放宽尺寸条件,得到了一类具有分数次积分性质的次线性算子从Herz型Hardy空间到(弱)Herz型Hardy空间有界性的判定条件,以及端点处的弱型估计.

By enlarging the size condition, the boundlessness of some sublinear operators, which has the characteristic of fractional integral, from Herz type spaces to （weak） Herz type Hardy spaces the weak estimation at the endpoint is obtained.
