International audienceWe state and analyze a generalization of the ''truncation trick'' suggested by Gourdon and Sebah to improve the performance of power series evaluation by binary splitting. It follows from our analysis that the values of D-finite functions (i.e., functions described as solutions of linear differential equations with polynomial coefficients) may be computed with error bounded by 2^(-p) in time Ο(p*(lg p)^(3+o(1))) and space Ο(p). The standard fast algorithm for this task, due to Chudnovsky and Chudnovsky, achieves the same time complexity bound but requires Θ(p*lg p) bits of memory.Nous énonçons et analysons une généralisation de " l'astuce des troncatures " proposée par Gourdon et Sebah afin d'améliorer les performances...
