81Burrows-Wheeler transform — The Burrows Wheeler transform (BWT, also called block sorting compression), is an algorithm used in data compression techniques such as bzip2. It was invented by Michael Burrows and David Wheeler in 1994 while working at DEC Systems Research… …
82Local homeomorphism — In topology, a local homeomorphism is a map from one topological space to another that respects locally the topological structure of the two spaces. More precisely, a continuous map f : X rarr; Y is a local homeomorphism if for every point x of X …
83Algebra homomorphism — A homomorphism between two algebras over a field K , A and B , is a map F:A ightarrow B such that for all k in K and x , y in A ,* F ( kx ) = kF ( x )* F ( x + y ) = F ( x ) + F ( y )* F ( xy ) = F ( x ) F ( y )If F is bijective then F is said to …
84Motor variable — A function of a motor variable is a function with arguments and values in the split complex number plane, much as functions of a complex variable involve ordinary complex numbers. The split complex numbers lie in the motor plane D, a term… …
85Computable isomorphism — In computability theory two sets A and B are computably isomorphic or recursively isomorphic if there exists a bijective computable function f with f(A) = B. Two numberings ν and μ are called computably isomorphic if there exists a bijective… …
86Outline of discrete mathematics — The following outline is presented as an overview of and topical guide to discrete mathematics: Discrete mathematics – study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have… …
87Parity of a permutation — Permutations of 4 elements Odd permutations have a green or orange background. The numbers in the right column are the inversion numbers (sequence …
88Compresión de Burrows-Wheeler — La Transformación de Burrows–Wheeler (BWT del inglés Burrows–Wheeler transform, también conocida como compresión por ordenación de bloques), es un algoritmo usado en técnicas de compresión de datos como en bzip2. Fue inventado por Michael Burrows …
89Brouwer fixed point theorem — In mathematics, the Brouwer fixed point theorem is an important fixed point theorem that applies to finite dimensional spaces and which forms the basis for several general fixed point theorems. It is named after Dutch mathematician L. E. J.… …
90List of basic discrete mathematics topics — Discrete mathematics, also called finite mathematics, is the study of mathematical structures that are fundamentally , in the sense of not supporting or requiring the notion of continuity. Most, if not all, of the objects studied in finite… …
