扇形算子的函数演算及相关函数理论

Functional calculi for sectorial operators and related function theory

Charles Batty, Alexander Gomilko, Yuri Tomilov

摘要:

本文构造了巴拿赫空间上扇形算子的两个有界泛函演算,通过扩充函数类、推广和锐化估计以及从扇形性的角度对函数演算进行调整,改进了解析Besov函数的谓词演算.演算是基于适当的再生公式,他们是兼容的标准功能演算,他们承认适当的收敛引理和谱映射定理定理。为了实现这一点,我们开发的理论相关联的函数空间的方式是有趣的和有意义的。作为我们的演算的后果,我们得出几个著名的运营商的范数估计,并提供其中一些推广。

英文摘要:

We construct two bounded functional calculi for sectorial operators on Banach spaces, which enhance the functional calculus for analytic Besov functions, by extending the class of functions, generalizing and sharpening estimates, and adapting the calculus to the angle of sectoriality. The calculi are based on appropriate reproducing formulas, they are compatible with standard functional calculi and they admit appropriate convergence lemmas and spectral mapping theorems. To achieve this, we develop the theory of associated function spaces in ways which are interesting and significant. As consequences of our calculi, we derive several well-known operator norm-estimates and provide generalizations of some of them.
