In topology, knot theory is the study of mathematical inspired by knots which appear in daily life, such as those in shoelaces and rope, a mathematical knot differs in that the ends are joined together so that it cannot be undone, the simplest knot being a ring (or "unknot").In mathematical language, a knot is an embedding of a circle in 3-dimensional Euclidean space, . In Euclideann-space,E n, how may disjoint, open, congruentn-spheres be located to maximize the fraction of the volume ofE n that then-spheres cover?That is the sphere packing problem, which goes back to a book review that Gauss wrote in , in which he pointed out that a problem concerning the minimal nonzero value assumed by a positive definite quadratic form .

An $[ {M,n} ]$ group code for the Gaussian channel is odd if it is nonplanar and both M and n are odd. Using the structure of the finite subgroups of the group of proper rotations in $\mathbb{R}^3$ we show that there exist odd $[ {M,n} ]$ group codes if and only if n does not equal by: 4.

In North-Holland Mathematical Library, Balanced codes.

A binary code C with K codewords is called balanced if in each coordinate both 0 and 1 appear at least [K/2] times. It is conjectured that among the binary (n, K)R codes with K = K(n, R) there is always a balanced denote by K i (a) the number of times a appears in the i-th coordinate in the.

Students and general readers who want a solid grounding in the fundamentals of space would do well to let M. Helena Noronha's Euclidean and Non-Euclidean Geometries be their guide.

Lattice packings correspond to linear codes. There are other, subtler relationships between Euclidean sphere packing and error-correcting codes. For example, the binary Golay code is closely related to the dimensional Leech lattice. For further details on these connections, see the book Sphere Packings, Lattices and Groups by Conway and Sloane.

Generate Sphere Packings in Arbitrary Euclidean Dimension. Instructions and source code. Please cite the following if you use this code: M. Skoge, A. Donev, F. Stillinger and S. Torquato, Packing Hyperspheres in High-Dimensional Euclidean Spaces, Physical Review E 74, ().

This webpage contains source codes of C++ programs to generate hard. There are reasonably self-contained introductions to several fundamental mathematical objects such as the Fano projective plane, finite fields, and linear groups, as well as very accessible and concrete introductions to the principal characters in the book such as error-correcting codes, sphere packings and Euclidean lattices.

This book is a. The main themes. This book is mainly concerned with the problem of packing spheres in Euclidean space of dimensions 1,2,3,4,5, Given a large number of equal spheres, what is the most efficient (or densest) way to pack them together.

We also study several closely related problems: the kissing number problem, which asks how many spheres can be arranged so. Upper bounds on the minimum distance of spherical codes Article (PDF Available) in IEEE Transactions on Information Theory 42(5). Series: North-Holland Mathematical Library.

A collection of congruent spheres in-dimensional Euclidean space is called a sphere packing if no two of the spheres have an interior point in common.

The packing density or simply density of a sphere packing is the fraction of space covered by the spheres. We will call.The second edition of this timely, definitive, and popular book continues to pursue the question: what is the most efficient way to pack a large number of equal spheres in n-dimensional Euclidean space?

The authors also continue to examine related problems such as the kissing number problem, the covering problem, the quantizing problem, and the classification of lattices and .Codes on Euclidean spheres are often referred to as spherical codes. They are of interest from mathematical, physical and engineering points of view.

Mathematically the topic belongs to the realm of algebraic combinatorics, with close connections to number theory, geometry, combinatorial theory, and - of course - to algebraic coding theory.
