Title: 2D BROWNIAN-MOTION IN A SYSTEM OF REFLECTING BARRIERS - EFFECTIVE DIFFUSIVITY BY A SAMPLING METHOD
Abstract: We study two-dimensional Brownian motion in an ordered periodic system linear reflecting barriers using the sampling method and conformal We calculate the effective diffusivity for the Brownian When the periods are fixed but the length of the barrier goes zero, the effective diffusivity in the direction perpendicular to the differs from the standard one by a term of order epsilon2 where epsilon is the length of a barrier.
