First passage time brownian motion

WebJul 14, 2016 · The question addressed is the precise relation between the standard first passage time and an alternative notion, which we call the first passage of the second kind, as suggested by Hurd (2007) and others. We are able to prove that the standard first passage time is the almost-sure limit of iterations of the first passage of the second kind. http://rhsdashboard.weebly.com/uploads/9/6/6/4/9664402/science_-_space_mining.pdf
