WebA special case of the preceding model is that of one-dimensional Brownian motion (p= 1) with a point barrier b(t) which is a linear function of time, as follows. b(t)==,8(l -t) (1.3) Here ,8=b(0)>0 and, generally, 6>0. The first passage time in this case has an inverse Gaussian distribution IG(u, A) with ,u= l/d and A=/J2. Here i is the mean ... One of the simplest and omnipresent stochastic systems is that of the Brownian particle in one dimension. This system describes the motion of a particle which moves stochastically in one dimensional space, with equal probability of moving to the left or to the right.
