讨论单位圆盘中Dirichlet空间上Toeplitz算子的性质,给出了Dirichiet空间上以一类连续函数为符号的Toeplitz算子满足亚正规性的充分必要条件.
討論單位圓盤中Dirichlet空間上Toeplitz算子的性質,給齣瞭Dirichiet空間上以一類連續函數為符號的Toeplitz算子滿足亞正規性的充分必要條件.

In this paper, we study tile hyponormality of Toeplitz operators on the Dirich- let space of the unit disk, and give some necessary and sufficient conditions for the hy- ponormality of Toeplitz operators with a class of continuous symbols on Dirichlet space.
