The classical Cauchy-Hadamard, Abel and Tauber theorems provide
useful information on the convergence of the power series in complex plane.
In this paper we prove analogous theorems for series in the generalized
Lommel-Wright functions with 4 indices. Results for interesting special
cases of series involving Bessel, Bessel-Maitland, Lommel and Struve functions,
are derived.We provide also a new asymptotic formula for the...

In studying the behaviour of series, defined by means of the Mittag-Leffler functions, on the boundary of its domain of convergence in the complex plane, we prove Cauchy-Hadamard, Abel, Tauber and Littlewood type theorems. Asymptotic formulae are also provided for the Mittag-Leffler functions in the case of " values of indices that are used in the proofs of the convergence theorems for the considered...

We consider some families of 3-index generalizations of the classical Mittag-Le²er functions and study the behaviour of these functions in domains of the complex plane. First, some inequalities in the complex plane and on its compact subsets are obtained. We also prove an asymptotic formula for the case of "large" values of the indices of these functions. Similar results have also been obtained by the author for the classical Bessel functions and...
