The boundedness of these operators on various spaces of analytic functions on $\mathbb{D}$ is well understood. The original motivation for this work is to understand the boundedness of compositions of two of these operators, for example $T_g^2, T_g S_g, M_g T_g$, etc. Our methods yield a characterization of the boundedness of a large class of operators contained in the algebra generated by these analytic paraproducts acting on the classical weighted Bergman and Hardy spaces in terms of the symbol $g$. In some cases it turns out that this property is not affected by cancellation, while in others it requires stronger and more subtle restrictions on the oscillation of the symbol $g$ than the case of a single paraproduct.27 p.application/pdfengcc-by-nc-nd (c) Elsevier Masson, 2022https://creativecommons.org/licenses/by-nc-nd/4.0/Funcions de diverses variables complexesEspais de HardyTeoria d'operadorsOperadors integralsFunctions of several complex variablesHardy spacesOperator theoryIntegral operatorsinfo:eu-repo/semantics/article7160322023-02-08info:eu-repo/semantics/openAccess
