Carleson-type embeddings with closed range

  • Konstantin M. Dyakonov

摘要

We characterize the Carleson measures \(\mu \) μ on the unit disk for which the image of the Hardy space \(H^p\) H p under the corresponding embedding operator is closed in \(L^p(\mu )\) L p ( μ ) . In fact, a more general result involving (pq)-Carleson measures is obtained. A similar problem is solved in the setting of Bergman spaces.
