Abstract
In this paper, we generalize several inequalities involving powers of the Davis-Wielandt radius for off-diagonal part of operator matrices of the form , where B and C are two bounded linear operators. We also obtain some new upper and lower bounds for the Davis-Wielandt radius of bounded linear operators, which generalize the existing ones.
