An algorithm for the approximate calculation of the coefficients of the Dulac series (asymptotic series of the monodromy transformation) in the space of vector fields with a Newton diagram containing more than one edge and a monodromic singular point is proposed. The conditions for the applicability of this algorithm are obtained. The algorithm is implemented in the MAPLE package. Examples are given for the case of a Newton diagram consisting of two edges.
Mots-clés : Monodromic singular point, monodromy transformation
Keywords: focus, center, Dulac series, correspondence mapping, Newton diagram, asymptotic representation, Hadamard integral.
