Some questions about the spectrum of single weighted hyperbolic composition operators are discussed, and results related with them in the literature are completed or partly extended. Also, our results on the weighted hyperbolic group are applied to the spectral study of two families of multiparameter weighted averaging operators, which generalize both Siskakis' operator and the reduced Hilbert matrix operator. info:eu-repo/grantAgreement/ES/DGA/E26-17R info:eu-repo/grantAgreement/ES/DGA/E48-23R info:eu-repo/grantAgreement/ES/MICINN/PID2019-10579GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2022-137294NB-I00 info:eu-repo/grantAgreement/ES/MINECO/BES-2017-081552 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 1.5 2024 MATHEMATICS 60 / 492 = 0.122 2024 Q1 T1 2.094 2024 Mathematics (miscellaneous) 2024 Q1 3.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Galé, José E.
