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