We give an approximation result in a modulus type distance, up to the second order, by means of a sequence of rough paths lying above elements of the reproducing kernel Hilbert space.28 pagesProbabilityPrimary 60G15; Secondary 60H05, 60H07Approximation of rough paths of fractional Brownian motiontext
