WebE of every point on the sphere, or the number of steps taken until caps of geodesic radius E about these points cover 2p. Call this the two-cap problem for the random walk. There is an analogous one-cap problem, the number of steps taken until caps of radius E about the points visited (and not their reflections) cover 2p. WebSep 2, 2007 · Given a sphere of any radius r in an n -dimensional Euclidean space, we study the coverings of this sphere with solid spheres of radius one. Our goal is to design a covering of the lowest covering density, which defines the average number of solid spheres covering a point in a bigger sphere.
