$H^2$上的本质正规复合算子

Essentially Normal Composition Operators on $H^2$

Mor Katz

摘要:

本文证明了单位圆盘上相当大的一类解析自映射所诱导的Hardy空间上的复合算子的本质正规性的一个简单判据。通过将该准则与边界Carathéodory-Fejér插值理论相结合,我们给出了诱导本质正规复合算子的单位圆盘上所有有理自映射的参数化.

英文摘要:

We prove a simple criterion for essential normality of composition operators on the Hardy space induced by maps in a reasonably large class of analytic self-maps of the unit disk. By combining this criterion with boundary Carathéodory-Fejér interpolation theory, we exhibit a parametrization for all rational self-maps of the unit disk which induce essentially normal composition operators.
