Abstract

The analytic and formal solutions of certain family of qq-difference-differential equations under the action of a complex perturbation parameter is considered. The previous study of the last two authors provides information in the case when the main equation under study is factorizable, as a product of two equations in the so-called normal form. Each of them gives rise to a single level of qq-Gevrey asymptotic expansion. In the present work, the main problem under study does not suffer any factorization, and a different approach is followed. More precisely, we lean on the technique developed in a paper, where the first author makes distinction among the different qq-Gevrey asymptotic levels by successive applications of two qq-Borel-Laplace transforms of different orders both to the same initial problem and which can be described by means of a Newton polygon.
