论文摘要
在本文中，我们完全表征何时两个双截断的Toeplitz运算符基本上是通勤，而两个双截断的Toeplitz oberators的半通信器紧凑。我们的主要思想是通过Hankel操作员，Toeplitz运算符和功能代数来研究双重截断的Toeplitz操作员。
In this paper, we completely characterize when two dual truncated Toeplitz operators are essentially commuting and when the semicommutator of two dual truncated Toeplitz operators is compact. Our main idea is to study dual truncated Toeplitz operators via Hankel operators, Toeplitz operators and function algebras.
