WebReﬂected Brownian motion on the half line [0,∞) is a way of keeping Brownian motion in the half line [0,∞). It can be deﬁned as the unique process Px supported on Ω = C[[0,∞);[0,∞)] … WebAbstract We are concerned with the stationary distribution of reflected Brownian motion (RBM) in a d d -dimensional domain G G. Such a process behaves like Brownian motion with a constant drift vector μ μ in G G and is instantaneously reflected at the boundary, with the direction of reflection given by a non-tangential vector field ν ν on ∂G ∂ G.

In this paper, a partial converse of a previous result on time-reversal of reflected Brownian motions is proved. Indeed, from [11], the time-reversal of a stationary reflected Brownian motion in a simple polyhedral domain is again a reflected Brownian motion if the directions of reflection satisfy a certain skew symmetry condition ...
