Composite Asymptotic Expansions and Difference Equations [PDF]
Revue Africaine de Recherche en Informatique et Mathématiques Appliquées, 2015 Difference equations in the complex domain of the form y(x+ϵ)−y(x)=ϵf(y(x))/y(x) are considered. The step size ϵ>0 is a small parameter, and the equation has a singularity at y=0. Solutions near the singularity are described using composite asymptotic expansions.
