我们给出了一种算法,该算法在 $\mathbb{Z}$ 上递归地构造一系列简单的随机游走,几乎肯定会收敛于布朗运动。通过相同的方法可以获得收敛到偏移、桥、曲流或归一化伪桥的简单随机游走的条件版本。
We give an algorithm which constructs recursively a sequence of simple random walks on $\mathbb{Z}$ converging almost surely to a Brownian motion. One obtains by the same method conditional versions of the simple random walk converging to the excursion, the bridge, the meander or the normalized pseudobridge.
