Keywords:
random walk, conditional Brownian motion, local time of conditional Brownian motions, functional limit theoremAbstract
An integer random walk {Si, i ≥ 0} with zero drift and finite variance σ2 is investigated. For a random pro-cess that assigns, to a variable u > 0, the number of hits of the specified random walk into the state \[\left\lfloor {u\sigma \sqrt n } \right\rfloor \] up to time n and is considered under the condition that S1 > 0, …, Sn – 1 > 0, Sn ≤ 0, a functional limit theorem concerning convergence in distribution of the process to the local time of a Brownian excursion is proved.
