摘要：
The content of this paper presents a fresh method of studying the Davis-Wielandt radius of bounded operators on Hilbert C & lowast;-modules. Using this method, we arrive at new results that improve upper and lower bounds for the Davis-Wielandt radius and generalize known theorems for bounded operators on Hilbert spaces to bounded adjointable operators on Hilbert C & lowast;-module spaces.
