摘 要: | 本文使用不变加权面积平均值性质刻画了单位圆盘内的调和函数.由此我们探讨了加权Bergman空间Ap(ψ)上的Toeplitz算子,给出了两个具有界调和符号的Toeplitz算子交换或本质交换的一些充要条件.

Commutators of Toeplitz Operators on Ap(ψ) |
| |
Abstract: | In this paper, we give a condition for harmonic functions in the unit disk by invariant weighted area-mean-value property. Then we investigate the commutators of Toeplitz operators on the weighted Bergman spaces Ap (ψ), characterize the bounded harmonic functions u and v on the unit disk for which the Toeplitz operators Tu and Tu are commuting or essentially commuting. |

Keywords: | weighted Bergman space Toeplitz operator commutator harmonic function |
