摘要：

We consider a singularly perturbed system of differential equations with irregular singular point. We prove that, in the general case of multiple elementary divisors, the corresponding asymptotic expansions can be constructed in the form of double series in fractional powers of the parameter and the ratio of the independent variable to the parameter.
