全Abel Toeplitz算子及其符号曲线的几何不变量

Totally Abelian Toeplitz operators and geometric invariants associated with their symbol curves

Hui Dan, Kunyu Guo, Hansong Huang

摘要:

本文主要研究Hardy空间和Bergman空间上解析Toeplitz算子背景下的全Abel算子。当符号是$\mathbb{C}$上的亚纯函数时,我们建立了这些算子的全阿贝尔性质与符号曲线几何性质之间的联系。发现符号曲线的卷绕数和自交重数在这一问题中起着重要的作用。本文运用了群论、复分析、几何学和算子理论等方法。作为一个副产品,在温和的条件下,我们提供了一个肯定的答案提出的问题,在\cite{BDU,T1},也构造了一些例子来表明,答案是否定的,如果相关的条件被削弱。

英文摘要:

This paper mainly studies totally Abelian operators in the context of analytic Toeplitz operators on both the Hardy and Bergman space. When the symbol is a meromorphic function on $\mathbb{C}$, we establish the connection between totally Abelian property of these operators and and geometric properties of their symbol curves. It is found that winding numbers and multiplicities of self-intersection of symbol curves play an important role in this topic. Techniques of group theory, complex analysis, geometry and operator theory are intrinsic in this paper. As a byproduct, under a mild condition we provides an affirmative answer to a question raised in \cite{BDU,T1}, and also construct some examples to show that the answer is negative if the associated conditions are weakened.
