Operator Fractional Brownian Sheet and Martingale Differences (1504.02203v2)
Published 9 Apr 2015 in math.PR
Abstract: In this paper, inspired by the fractional Brownian sheet of Riemann-Liouville type, we introduce the operator fractional Brownian sheet of Riemman-Liouville type, and study some properties of it. We also present an approximation in law to it based on the martingale differences.
