我们考虑成对的 3 维布朗路径,从原点开始,并在零时间后没有交点。我们证明,在这种条件下,路径对上存在一种独特的不变测量,同时提高了 Lawler (1998) 收敛到平稳性的速度。
We consider pairs of 3-dimensional Brownian paths, started at the ori- gin and conditioned to have no intersections after time zero. We show that there exists a unique measure on pairs of paths that is invariant under this conditioning, while improving the rate of convergence to stationarity from Lawler (1998).
