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.
