摘要
The inverse first-passage problem for a Wiener process (W(t))(t >= 0) seeks to determine a function b : R(+) -> R such that tau = inf{t > 0 vertical bar W(t) >= b(t)} has a given law. In this paper two methods for approximating the unknown function b are presented. The errors of the two methods are studied. A set of examples illustrates the methods. Possible applications are enlighted.
