Numerical scheme for stochastic differential equations driven by fractional Brownian motion with 1/4 < H < 1/2

Abstract: In this article, we study a numerical scheme for stochastic differential equations driven by fractional Brownian motion with Hurst parameter H in (1/4; 1/2). Towards this end, we apply Doss-Sussmann representation of the solution and an approximation of this representation using a first order Taylor expansion. The obtained rate of convergence is n^2H+rho, for rho small enough.
