摘要:
Assume that X is a continuous square integrable process with zero mean, defined on some probability space (Omega, F, P). The classical characterization due to P. Levy says that X is a Brownian motion if and only if X and X-t(2) - t, t >= 0, are martingales with respect to the intrinsic filtration F-X. We extend this result to fractional Brownian motion.
