Asymptotics of first-passage time over a one-sided stochastic boundary
We study the asymptotic behavior of the first-passage times for Brownian motion, L'evy 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 sufficient conditions for $t^{; ; -1/2}; ; $ asymptotics, and obtain exact asymptotics for linear functions.
