On the maximum of discretely sampled fractional Brownian motion with small Hurst parameter

Probability 2018-02-13 v1

Abstract

We show that the distribution of the maximum of the fractional Brownian motion BHB^H with Hurst parameter H0H\to 0 over an nn-point set τ[0,1]\tau \subset [0,1] can be approximated by the normal law with mean lnn\sqrt{\ln n} and variance 1/21/2 provided that nn\to \infty slowly enough and the points in τ\tau are not too close to each other.
