Quasimetric space — In mathematics, a quasimetric space is a generalized metric space in which the metric is not necessarily symmetric. Although quasimetrics are common in real life, this notion is rarely used in mathematics, and its name is not entirely… … Wikipedia
Metric (mathematics) — In mathematics, a metric or distance function is a function which defines a distance between elements of a set. A set with a metric is called a metric space. A metric induces a topology on a set but not all topologies can be generated by a metric … Wikipedia
Hemimetric space — In mathematics, a hemimetric space is a generalization of a metric space, obtained by removing the requirements of identity of indiscernibles and of symmetry. It is thus a generalization of both a quasimetric space and a pseudometric space, while … Wikipedia
Color difference — The difference or distance between two colors is a metric of interest in color science. It allows people to quantify a notion that would otherwise be described with adjectives, to the detriment of anyone whose work is color critical. Common… … Wikipedia
Espace Quasimétrique — En mathématiques, un espace quasimétrique est un cas particulier d espace hémimétrique, qui généralise ainsi la notion d espace métrique ne nécessitant pas la condition de symétrie. De tels espaces apparaissent parfois en théorie des graphes.… … Wikipédia en Français

Espace quasimétrique — En mathématiques, la notion d espace quasimétrique généralise celle d espace métrique. Les quasidistances ou quasimétriques, non nécessairement symétriques, sont fréquentes dans la vie courante, mais rarement utilisées en mathématiques, et le… … Wikipédia en Français

Information theory — Not to be confused with Information science. Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. Information theory was developed by Claude E. Shannon to find fundamental… … Wikipedia
Metric space — In mathematics, a metric space is a set where a notion of distance (called a metric) between elements of the set is defined. The metric space which most closely corresponds to our intuitive understanding of space is the 3 dimensional Euclidean… … Wikipedia
Sierpiński space — In mathematics, Sierpiński space (or the connected two point set) is a finite topological space with two points, only one of which is closed.It is the smallest example of a topological space which is neither trivial nor discrete. It is named… … Wikipedia
