Norms of Derivations Implemented by S-Universal Operators
(International Journal of Mathematical Analysis, 2011)
Let H be a complex Hilbert space and B(H) the algebra of all
bounded linear operators on H. For A, B ∈ B(H), we define inner
derivations implemented by A,B respectively on B(H) by ΔA(X) =
AX−XA, ΔB(X) = BX−XB and a ...
On the Generalized Reid Inequality and the Numerical Radii
(Applied Mathematical Sciences, 2011)
In this paper, we extend the generalized Reid inequality to include
the numerical radii for the product of two Hilbert space operators.
