In this paper we investigate several convergent and/or asymptotic expansions of Hp(z,b,η) for some limiting values of their variables and parameters: large values of z, large values of p, small values of η, and values of b→1. We provide explicit and/or recursive algorithms for the computation of the coefficients of the expansions. Some numerical examples illustrate the accuracy of the approximations. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.7 2023 MATHEMATICS 218 / 490 = 0.445 2023 Q2 T2 MATHEMATICS, APPLIED 237 / 332 = 0.714 2023 Q3 T3 0.597 2023 Applied Mathematics 2023 Q2 Analysis 2023 Q2 2.2 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion López, José L.
