研究了Hardy空间上Cesàro算子的有界性.证明极大Cesàro算子的强型和弱型有界估计,其弱有界性估计是精确的.推广和加强了已有研究结果.
The paper deals with the boundedness of the Cesàro operator on Hardy spaces. The strong and weak type estimates for the boundedness of the Cesàro operator on Hardy spaces are obtained. It is proved that the weak type estimate is sharp. Some known results are extended and strengthened.
