摘要
漂移为 μ 的布朗粒子在水平 a > 0 时撞击吸收体，其第一次通过时间 (FPT) Ta 的分布是众所周知的，由其密度 γ(t)=a2πt3e-(a-μt)22t 给出......
First-passage time distribution of a Brownian motion: two unexpected journeys
The distribution of the first-passage time (FPT) Ta for a Brownian particle with drift μ subject to hitting an absorber at a level a > 0 is well-known and given by its density γ(t)=a2πt3e−(a−μt)22t...
