Refinements of generalized Euclidean operator radius inequalities of 2-tuple operators

Functional Analysis 2024-08-14 v1

Abstract

We develop several upper and lower bounds for the AA-Euclidean operator radius of 22-tuple operators admitting AA-adjoint, and show that they refine the earlier related bounds. As an application of the bounds developed here, we obtain sharper AA-numerical radius bounds.
