Title: On S. Grivaux' example of a hypercyclic rank one perturbation of a unitary operator
Abstract: Recently, Sophie Grivaux showed that there exists a rank one perturbation of a unitary operator in a Hilbert space which is hypercyclic. We give a similar construction using a functional model for rank one perturbations of singular unitary operators.
