WebThe theory of first-passage times of Brownian motion is developed in general, and it is shown that for certain special boundaries—the only ones of any importance—mean first-passage times can be derived very simply, avoiding the usual method involving series. http://physics.gu.se/%7Efrtbm/joomla/media/mydocs/LennartSjogren/kap8.pdf
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 ... WebIf X (t) is Brownian motion in 2D, where X (0) = 0, then we can ask what is the expected time required to first hit a circle of radius R, centered at the origin. This is a First …
