Pau, JordiPerälä, Antti2023-02-242023-02-2420200002-9947https://hdl.handle.net/2445/194164We study a Toeplitz-type operator $Q_\mu$ between the holomorphic Hardy spaces $H^p$ and $H^q$ of the unit ball. Here the generating symbol $\mu$ is assumed to be a positive Borel measure. This kind of operator is related to many classical mappings acting on Hardy spaces, such as composition operators, the Volterra-type integration operators, and Carleson embeddings. We completely characterize the boundedness and compactness of $Q_\mu: H^p \rightarrow H^q$ for the full range $1<p, q<\infty$; and also describe the membership in the Schatten classes of $H^2$. In the last section of the paper, we demonstrate the usefulness of $Q_\mu$ through applications.32 p.application/pdfengcc-by-nc-nd (c) American Mathematical Society (AMS), 2020https://creativecommons.org/licenses/by-nc-nd/4.0/Funcions de diverses variables complexesFuncions holomorfesEspais de HardyTeoria d'operadorsFunctions of several complex variablesHolomorphic functionsHardy spacesOperator theoryinfo:eu-repo/semantics/article6999722023-02-24info:eu-repo/semantics/openAccess
