A note on Malliavin fractional smoothness for L\'evy processes and approximation

Probability 2012-01-04 v1

Abstract

Assume a L\'evy process XX on the time interval [0,1][0,1] that is an L2L_2-martingale and let YY be either its stochastic exponential or XX itself. We consider Riemann-approximations of certain stochastic integrals driven by YY and relate the L2L_2-approximation rates to the Malliavin fractional smoothness of the integral to be approximated. The Malliavin fractional smoothness is described by Besov spaces generated with the real interpolation method.
