凸区域与K-谱集

Convex domains and K-spectral sets

Catalin Badea, Michel Crouzeix, Bernard Delyon

摘要:

设$Ω$是复平面的开凸区域。研究了常数K使得$Ω$是K-谱或完全K-谱的连续线性希尔伯特空间算子,数值域包含在$Ω$中.讨论了几种方法。

英文摘要:

Let $Ω$ be an open convex domain of the complex plane. We study constants K such that $Ω$ is K-spectral or complete K-spectral for each continuous linear Hilbert space operator with numerical range included in $Ω$. Several approaches are discussed.
