ABSTRACT
In this paper, we study hyponormality of the dilation of truncated Toeplitz operators on . In particular, we provide necessary and sufficient conditions for the dilation of truncated Toeplitz operators to be hyponormal. Moreover, we investigate connections between hyponormal and normal dilations of truncated Toeplitz operators.

截断 Toeplitz 算子膨胀的次规范性
摘要
在本文中,我们研究了截断 Toeplitz 算子的膨胀的次正态性 . 特别是,我们为截断的 Toeplitz 算子的扩张是次正态提供了充分必要条件。此外,我们研究了截断的 Toeplitz 算子的次正态和正态膨胀之间的联系。
