Discrete approximation of stochastic integrals with respect to fractional Brownian motion of Hurst index H>1/2.

In this paper we provide a discrete approximation for the stochastic integral with respect to the fractional Brownian motion of Hurst index H>1/2 defined in terms of the divergence operator. To determine the suitable class of integrands for which the approximation holds, we also investigate the relations among the spaces of Malliavin differentiable processes in the fractional and standard case.
