摘要:

该文研究了Dirichlet空间Dp~(1< p<∞)上Toeplitz算子的紧性与Fredholm性质, 计算了Dp上Toeplitz算子的Fredholm指标. 还考查了Dp上Hankel算子紧性.

关键词: Dirichlet空间, Toeplitz 算子, 紧性, Fredholm指标

Abstract:

In this paper, we investigate the compactness and the Fredholm properties of Toeplitz operators on the Dirichlet space Dp(D) (1 < p < ∞), where D is the unit disc in complex plane C. We also compute the Fredholm index of Toeplitz operator on Dirichlet space Dp(D).

Key words: Toeplitz operators, Compactness,  Dirichlet space, Fredholm index
