摘要
本文研究了复平面中单位圆盘D上不同Hardy空间之间的加权复合算子 .利用Car leson测度的概念分别给出了有界或紧的加权复合算子的充分必要条件 .本文也用角导数的概念给出了紧加权复合算子的一个必要条件 .
In this paper,we study weighted composition operators between Hardy spaces,induced by a fixed analytic function and an analytic self map of the open unit disk,and give the sufficient and necessary conditions,in terms of the concept of Carleson measure,for the weighted composition operator to be bounded and compact respectively.We also give a necessary condition of compact weighted composition operator in terms of the angular derivative of the inducing maps.
