| Résumé : | This book is mainly concerned with the problem of packing spheres in euclidean space of dimesions 1,2,3,4... given a large numbrer of equal spheres, what is the most efficient way to pack them together ? we also study several closely related problems : the kissing numbrer problem, which asks how many sphers can be arranged so that thely all touch one central sphere of the same size; the covering problem, which asks for the least dense way to cover n-dimensional space with equal overlapping spheres; and the quantizing problem, important for applications to analog-to-digital conversion, which asks how to place points in space so that average second moment of their their voronoi cells is as small as possible. |
