Abstract: An operator $ T$ on a Hilbert space $ \mathcal{H}$ is said to have the transitive algebra property if $ \mathcal{L}(\mathcal{H})$ is the only transitive operator algebra which contains $ T$. It was shown by Arveson that the unilateral shift has this property. It is the purpose of the present paper to show that perturbations of the unilateral shift by a large class of finite rank operators have the transitive algebra property. Our results are partial solutions of the well-known transitive algebra problem.
