摘要:

$\varphi$ 是复平面${\Bbb C}$中单位圆盘 ${\Bbb D}$上的解析自映射. 该文刻画了一般Hardy型空间$H^{p,q,s}({\Bbb D})$上使得复合算子$C_{\varphi}$有界或者紧时的符号函数 $\varphi$.

关键词: 复合算子, 有界性, 紧性, 一般 Hardy 型空间, 单位圆盘

Abstract:

Let $\varphi$ be an analytic self-map of the unit disc ${\Bbb D}$ in the complex plane ${\Bbb C}$. In this paper, the authors characterize those symbols $\varphi$ such that composition operators $C_{\varphi}$ are bounded or compact on the general Hardy type space $H^{p,q,s}({\Bbb D})$.

Key words: Composition operator, Boundedness, Compactness, General Hardy type space, Unit disc
