- W2119622857 abstract "Let H be a separable infinite dimensional complex Hilbert space, and let L(H) denote the algebra of all bounded linear operators on H. Let A,B 2 L(H) we define the generalized derivation A,B : L(H) 7! L(H) by A,B(X) = AX XB, we note A,A = A. If for all X 2 L(H) and for all T 2 ker A the inequality ||T (AX XA)|| || T||(*) holds, then we say that the range of A is orthogonal to kernel A in the sense of Birkho. The operator A 2 L(H) is said to be finite (17) if ||I (AX XA)|| 1(**) for all X 2 L(H), where I is the identity operator. The well-known Inequality (**) due to J.P.Williams (17) is the starting point of the topic of commutator approximation (a topic which has its roots in quantum theory (18)). This topic deals with minimizing the distance, measured by some norms or other, between a varying commutator XX X X and some fixed operator (12). In this paper we prove that a paranormal operator is finite and we present some generalized finite operators. An extension of Inequality (*) is also given." @default.
