First passage time brownian motion
WebOne way to deal with this is to consider a more general Brownian motion X(W) x W(W), where W(W) is the Wiener process with W(0){0 and x!0 is the initial condition. Let T inf{W: X(W) 0} denote the first passage time to the origin, max ( ) 0 W W M X d dT the maximum value reached during the first passage, and A X WdW ³ T 0 ( ) the first passage ... WebJan 1, 2000 · We study the asymptotic behavior of the first-passage times for Brownian motion, Lévy processes and continuous martingales over one-sided increasing stochastic, as well as deterministic, boundaries. In particular, we study the first-passage time of a Brownian motion over the increasing function of its local time, give necessary and …

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. Given that Brownian motion is used often as a tool to … See more Events are often triggered when a stochastic or random process first encounters a threshold. The threshold can be a barrier, boundary or specified state of a system.
