Some new inequalities on the improvement of numerical radius bounds

Year: 2025

Type: article

Abstract: This article presents an investigation to improve the numerical radius bounds for bounded linear operators on a complex Hilbert space through the application of Young’s inequality. This study yields novel numerical radius bounds for operators, improves existing bounds, and achieves new refinements for the numerical radius bounds related to the sum and product of operators.
