Let H be a separable infinite-dimensional complex Hilbert space and let A B โ B H , where B H is the algebra of operators on H into itself. Let ฮด A B B H โ B H denote the generalized derivation ฮด AB X = AX -XB. This note considers the relationship between the commutant of an operator and the commuta
