On the Davis-Wielandt radius inequalities of Hilbert space operators

preprint2020arXivOpen access

Abstract

In this work, some new upper and lower bounds of the Davis-Wielandt radius are introduced. Generalizations of some presented results are obtained. Some bounds of the Davis-Wielandt radius for n×nn\times n operator matrices are established. An extension of the Davis-Wielandt radius to the Euclidean operator radius is introduced.
