2-D Brownian motion in a system of reflecting barriers: effective diffusivity by a sampling method by
We study two dimensional Brownian motion in an ordered periodic system of linear reflecting barriers using the sampling method and conformal transformations. We calculate the effective diffusivity for the Brownian particle. When the periods are fixed but the length of the barrier goes to zero, the effective diffusivity in the direction perpendicular to the barriers differs from the standard one...
متن کامل1Slow diffusion for a Brownian motion with random reflecting barriers
Let β be a positive number: we consider a particle performing a one dimensional Brownian motion with drift -β, diffusion coefficient 1, and a reflecting barrier at 0. We prove that the time R, needed by the particle to reach a random level X, has the same distribution tail as Γ(α+1)1/α e2βX/2β2, provided that one of these tails is regularly varying with negative index α. As a consequence, we di...
متن کاملMarkov-modulated Brownian Motion with Two Reflecting Barriers
We consider a Markov-modulated Brownian motion reflected to stay in a strip [0, B]. The stationary distribution of this process is known to have a simple form under some assumptions. We provide a short probabilistic argument leading to this result and explain its simplicity. Moreover, this argument allows for generalizations including the distribution of the reflected process at an independent,...

The Semimartingale Structure of Reflecting Brownian Motion
We prove that reflecting Brownian motion on a bounded Lipschitz domain is a semimartingale. We also extend the well-known Skorokhod equation to this case. In this note we study the semimartingale property and the Skorokhod equation of reflecting Brownian motion on a bounded Euclidean domain. A R d_ valued continuous stochastic process X = {Xt ; t > 0} is said to be a semimartingale if it can be...
