不同权的Bloch型空间之间的加权复合算子再刻画
CHARACTERIZATION OF WEIGHTED COMPOSITION OPERATORS BETWEEN DIFIERENT WEIGHTED BLOCH TYPE SPACES AGAIN

本文研究了单位圆中从空间βL到βα的加权复合算子uCφ为有界算子和紧算子的条件.利用阶估计等方法，获得了有界性和紧性的简捷充要条件，推广了叶善力的相应结果.
In the paper, the authors discuss the conditions that the weighted composition operator uCφ is a bounded operator or compact operator from the space βL to the space βα in the disc. By the way of order's estimation, the briefly su-cient condition and necessary conditions are given, which extend Ye Shanli's results
