Differentiability of stochastic flow of reflected Brownian motions
|
Krzysztof Burdzy, University of Washington |
Abstract
We prove that a stochastic flow of reflected Brownian motions
in a smooth multidimensional domain is differentiable with
respect to its initial position. The derivative is a linear map
represented by a multiplicative functional for reflected
Brownian motion. The method of proof is based on excursion
theory and analysis of the deterministic Skorokhod equation.
