Abstract: | Let W1 and W2 be two independent Wiener processes on a half-line, and let W(a)=(W1, aW2) (a≥1). We consider open neighborhoods of the initial point with uniform hitting distribution. This property uniquely determines
the form of a neighborhood. The main result is as follows: such a neighborhood has a limit form as a→∞. Properties of the
limit form are studied. Bibliography: 2 titles.
