A Milstein-type scheme without Levy area terms for SDEs driven by fractional Brownian motion
Annales de l'Institut Henri Poincaré (B) Probabilités et Statistiques 48, 2 (2012) 518-550
Abstract: In this article, we study the numerical approximation of stochastic differential equations driven by a multidimensional fractional Brownian motion (fBm) with Hurst parameter greater than 1/3. We introduce an implementable scheme for these equations, which is based on a second order Taylor expansion, where the usual Levy area terms are replaced by products of increments of the driving fBm. The convergence of our scheme is shown by means of a combination of rough paths techniques and error bounds for the discretisation of the Levy area terms.
