%0 Journal Article %T Multiplicative functional for reflected Brownian motion via deterministic ODE %A Krzysztof Burdzy %A John M. Lee %J Mathematics %D 2008 %I arXiv %X We prove that a sequence of semi-discrete approximations converges to a multiplicative functional for reflected Brownian motion, which intuitively represents the Lyapunov exponent for the corresponding stochastic flow. The method of proof is based on a study of the deterministic version of the problem and the excursion theory. %U http://arxiv.org/abs/0805.3740v1
