摘要：
In this paper, we present a method of computation of formal solutions of scalar singularly perturbed linear differential equations, based on an analysis by a Newton polygon. The proposed algorithm has been implemented in Maple. It appears to be more efficient than the study of equivalent companion systems [9] [8] [10] [11]. It gives also a straight answer to the divergence of the computed series.
