双圆盘上Toeplitz算子的半交换子

The semi-commutator of Toeplitz operators on the bidisc

Caixing Gu, Dechao Zheng

摘要:

本文刻画了两个Toeplitz算子$T_f$和$T_g$在双圆盘的Hardy空间上的半交换子$T_fT_g-T_{fg}$为零的条件.我们还证明了双圆盘上不存在非零有限秩半交换子。此外,还给出了符号在双环$T^2$上连续的紧半交换子的显式例子。

英文摘要:

In this paper we characterize when the semi-commutator $T_fT_g-T_{fg}$ of two Toeplitz operators $T_f$ and $T_g$ on the Hardy space of the bidisc is zero. We also show that there is no nonzero finite rank semi-commutator on the bidisc. Furthermore explicit examples of compact semi-commutators with symbols continuous on the bitorus $T^2$ are given.
