摘要
本文研究半直线上带渐近零漂移的紧邻随机游动.用M表示从1到0的一个游程内粒子的最大位置.本文研究M的分布,并刻划它的渐近分布,该结果与简单随机游动不同.
Consider a nearest-neighbor random walk with certain asymptotically zero drift on the positive half line.Let M be the maximum of an excursion starting from 1 and ending at 0.We study the distribution of M and characterize its asymptotics,which is quite different from those of simple random walks.
