Abstract

In this paper we introduce a definition of a multi-dimensional fractional Brownian motion of Hurst index H(0,1)H \in (0, 1) under volatility uncertainty (in short G-fBm). We study the properties of such a process and provide first results about stochastic calculus with respect to a fractional G-Brownian motion for a Hurst index H>12H >\frac{1}{2} .
