二维和三维的简单随机游动的相交指数给出了路径不相交的概率衰减率的度量。在本文中,我们证明了随机游动的相交指数与布朗运动的相交指数相同,并且证明了在距离n以内不相交的概率与n− 1相当(等于乘法常数)。
The intersection exponent ξ for simple random walk in two and three dimensions gives a measure of the rate of decay of the probability that paths do not intersect. In this paper we show that the intersection exponent for random walks is the same as that for Brownian motion and show in fact that the probability of nonintersection up to distance n is comparable (equal up to multiplicative constants) to n−ξ.
