dc.description.abstract | Let H be an infinite dimensional complex Hilbert space and B(H)
the algebra of all bounded linear operators on H. For two bounded
operators A, B ∈ B(H), the map δAB : B(H) → B(H) is a generalized
inner derivation operator induced by A and B defined by δAB(X) =
AX − XB (1)
In this paper we show that the norm of a generalized inner derivation
operator is given by k(δAB/B(B(H)))k = kAk+kBk for all A, B ∈ B(H).
