Weak Approximation of G-Expectations (1103.0575v1)
Published 2 Mar 2011 in math.PR and math.OC
Abstract: We introduce a notion of volatility uncertainty in discrete time and define the corresponding analogue of Peng's G-expectation. In the continuous-time limit, the resulting sublinear expectation converges weakly to the G-expectation. This can be seen as a Donsker-type result for the G-Brownian motion.
