摘要:

该文研究了单位球Hardy空间上非自同构线性分式加权复合算子的交换子.首先给出加权复合算子的交换子公式.然后根据线性分式映射的三种类型刻画交换子的紧性.最后得到当线性分式映射为抛物型时,交换子是紧的.

关键词: Hardy空间, 加权复合算子, 交换子

Abstract:

In this paper, we study commutators of weighted composition operators with linear fractional non-automorphisms on Hardy space of the unit ball. First, we obtain the formula of commutators of weighted composition operators. Then, we characterize compactness of commutators according to two special situations of linear fractional maps. Finally, we obtain that commutators are compact when linear fractional maps are parabolic and commutators are not compact when linear fractional maps are hyperbolic.

Key words: Hardy spaces, Weighted composition operators, Commutators
