Bounded point evaluation for operators with the wandering subspace property
Abstract
We extend and study the notion of bounded point evaluation introduced by Williams for a cyclic operator to the class of operators with the wandering subspace property. We characterize the set of all bounded point evaluations for an operator with the wandering subspace property in terms of the invertibility of certain projections. This result generalizes the earlier established characterization of for a finitely cyclic operator . Further, if is a left-invertible operator with the wandering subspace property, then we determine the and the set of all analytic bounded point evaluations for . We also give examples of left-invertible operator with the wandering subspace property for which , where is the spectral radius of the Cauchy dual of .
