摘要: The first-passage-time problem for a Brownian motion with alternating infinitesimal moments through constant boundary is considered under the assumption that time intervals between consecutive changes of these are described by an renewal process. Bounds to density and distribution function obtained, simulation procedure estimate densities constructed. Examples applications problems in environmental sciences mathematical finance also provided.
