Dragomir, Sever S (2005) New Reverse Inequalities for the Numerical Radius of Normal Operators in Hilbert Spaces. Research report collection, 8 (Supp).

Abstract

In this paper, more inequalities between the operator norm and its numerical radius, for the class of normal operators, are established. Some of the obtained results are based on recent reverse results for the Schwarz inequality in Hilbert spaces due to the author.
