Abstract
The topic of this paper is formal solutions of linear differential equ ations with formal power series coefficients. The method proposed for computing these solutions is based on factorization of differential op erators. The notion of exponential parts is introduced to give a descr iption of factorization properties and to characterize the formal solu tions. The algorithms will be described and their implementation is av ailable. (C) 1997 Academic Press Limited.
