Abstract: | In this paper we calculate the exact asymptotics of the probability P{‖w(t)+uct‖
p
>u},u→∞, wherew(t) is the standard Wiener process and ‖x‖
p
is the ordinary norm in the spaceL
p0,1],p≥2. The result is obtained on the basis of a general theorem due to the author on the asymptotics of the Gaussian measureP(uD),u→∞, for a Borel setD belonging to a separable Banach space.
