In this paper, we study weighted composition operators and differences of composition operators. We use the Carleson measure to estimate the operator norm and the essential norm of those operators which act between two Bergman spaces with Békollé weights.

加权复合算子及加权伯格曼空间之间复合算子的差异

在本文中，我们研究了加权组合算子和组合算子的差异。我们使用 Carleson 测度来估计算子范数和那些在两个带有 Békollé 权重的伯格曼空间之间起作用的算子的基本范数。
