Abstract

We study a linear qq-difference-differential Cauchy problem, under the action of a perturbation parameter ϵ\epsilon. This work deals with a qq-analog of the research made in a previoues work, giving rise to a generalization of a recent work by the second author. This generalization is related to the nature of the forcing term which suggests the use of a qq-analog of an acceleration procedure. The proof leans on a qq-analog of the so-called Ramis-Sibuya theorem which entails two distinct qq-Gevrey orders. The work concludes with an application of the main result when the forcing term solves a related problem.
