Milstein's type schemes for fractional SDEs
Annales de l'I.H.P. Probabilités et statistiques, Tome 45 (2009) no. 4, pp. 1085-1098.

On étudie la vitesse exacte de convergence de certains schémas d'approximation associés à des équations différentielles stochastiques scalaires dirigées par le mouvement brownien fractionnaire B. On utilise le comportement asymptotique des variations à poids de B, et la limite de l'erreur entre la solution et son approximation est calculée de façon explicite.

Weighted power variations of fractional brownian motion B are used to compute the exact rate of convergence of some approximating schemes associated to one-dimensional stochastic differential equations (SDEs) driven by B. The limit of the error between the exact solution and the considered scheme is computed explicitly.
