摘要
对于暂留Brown运动,我们给出了极大游程与极小游程的若干定义,并且求出了 极大游程(极小游程)的分布,以及极大游程(极小游程)与首达极大时(首达极小时)的联 合分布.作为推论求出了首达极大时与首达极小时的分布.
For a transient Brownian motion, we give some definitions of maximum excursion and infimum excursion. We obtain their distributions, and the joint distributions of maximum (infimum) excursion and the first instance of attaining such a maximum (infimum). As a consequence, we obtain the distribution functions of the first instance of attaining such a maximum and the first instance of attaining such a infimum.
