摘要

我们提供了格什高林圆定理的一个变体，在这个变体中，"-估计值 "被换成了"-估计值"，更适合于无穷维希尔伯特空间环境。

A Hilbert-space variant of Geršgorin's circle theorem

We provide a variant of Geršgorin's circle theorem, where the $ℓ^{1}$ -estimates are swapped for $ℓ^{2}$ -estimates, more suitable for the infinite-dimensional Hilbert space setting.
