On Bounds for Packings on a Sphere and in Space
G. A. Kabatiansky, V. I. Levenshtein
Abstract:
A method is proposed for obtaining bounds for packings in metric spaces, the method being based on the use of zonal spherical functions associated with a motion group of the space. For the maximum number M(n,Θ)M(n,Θ) of points of a unit sphere of nn-dimensional Euclidean space at an angular distance of not less than ΘΘ from one another, the method is used to obtain an upper bound that is better than the available ones for any fixed Θ(0<Θ<π/2)Θ(0<Θ<π/2) and n→∞n→∞ This bound yields a new asymptotic upper bound for dn, namely, the maximum packing density of an nn-dimensional Euclidean space by equal balls.
