In studying the behaviour of series defined by means of the Le Roy type functions, we prove Cauchy–Hadamard type theorems. Asymptotic formulae for these new special functions in the cases of `large' values of indices are also provided, as necessary in the proofs of the convergence theorems for the considered series in the complex plane.
