Abstract:
A bounded linear operator $A$ on a Hilbert space $\mathcal {H}$ is called reflexive if any bounded linear operator which leaves invariant the invariant subspaces of $A$ is a limit of polynomials in $A$ in the weak operator topology. In this note we prove that every isometry $V$ on a Hilbert space $\mathcal {H}$ is reflexive.References
