Letbe a factor acting on a complex, separable Hilbert space. An operatoris said to be irreducible inif, the von Neumann subalgebra generated byin, is an irreducible subfactor of, ie,. In this note, we prove that each operatoris a sum of two irreducible operators in, which can be viewed as a natural generalization of a theorem in [Proc. Amer. Math. Soc. 21 (1969), pp. 251–252], with a completely different proof. References
