摘要

我们给出了希尔伯特空间上两个算子的欧氏算子半径的几个下限和上限。我们改进了一些早期的相关界值。此外,作为这些界值的应用,我们还推导出了经典数值半径的一些新界值。其中一些界值是对某些现有界值的改进。

Further bounds for the Euclidean operator radius of a pair of operators and their applications

We give several lower and upper bounds for the Euclidean operator radius of two operators on a Hilbert space. We improve some earlier related bounds. Also, as applications of these bounds, we deduce some new bounds for the classical numerical radius. Some of these bounds are refinements of certain existing bounds.
