A note on minimal envelopes of Douglas algebras, minimal support sets, and restricted Douglas algebras
We characterize the interpolating Blaschke products of finite type in terms of their support sets. We also give a sufficient condition on the restricted Douglas algebra of a support set that is invariant under the Bourgain map, and its minimal envelope is singly generated.
