Abstract:Ключевые слова и фразы: винеровский процесс, локальное вре мя, пересечения уровня, приращения.1. Introduction. Let X t = {X(t,cj), t £ [0,1], w e ft} be a standard Wiener process. For each t and e > 0 define A e (i) = e~1^2(X t+£ -X t ), the normalized increments of the process. If we fix a trajectory and consider A e (tf) as a random variable (r.v.) on t with Lebesgue's measure A then, as M. Wschebor showed [10], for almost every trajectory, this variable converges in distribution, as e goes to zero, to a Gau… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
