Abstract.
Let B(H) denote the algebra of all bounded linear operators on a separable infinite dimensional complex Hilbert space H into itself. Let A = (A1,A2,.., A n ) and B = (B1, B2,.., B n ) be n-tuples in B(H), we define the elementary operator \(E_{A,B} : B(H) \mapsto B(H)\) by \(E_{A,B} (X) = \Sigma _{i = 1}^n A_i X\,B_i. \) In this paper we initiate the study of some properties of the range of such operators.
