Summary
We say that the discD(α)⊂R 2, of radius α, located around the origin isp-covered in timeT by a Wiener processW(·) if for anyzεD(α) there exists a 0≦t≦T such thatW(t) is a point of the disc of radiusp, located aroundz. The supremum of those α's (α≧0) is studied for which,D(α) isp-covered inT.
