31Antikette — Der Begriff der Antikette (engl. antichain) ist ein Begriff der Mengenlehre und gehört zum Umfeld des Begriffs der Ordnungsrelation. Die Definition dieses Begriffs ist wie folgt: Eine Teilmenge A einer geordneten Menge (M, R) ist eine Antikette,… …
32Processus de Penrose — Dans le domaine de la physique des trous noirs, le processus de Penrose est le nom donné à un processus physique qui permet d extraire de l énergie d un trou noir en rotation (trou noir de Kerr ou trou noir de Kerr Newman). Il est nommé en l… …
33Équation du temps — L’équation du temps est un paramètre utilisé en astronomie pour rendre compte du mouvement apparent relatif du Soleil par rapport au soleil moyen, lesquels peuvent différer l un par rapport à l autre de plus ou moins un quart d heure environ. D… …
34Group (mathematics) — This article covers basic notions. For advanced topics, see Group theory. The possible manipulations of this Rubik s Cube form a group. In mathematics, a group is an algebraic structure consisting of a set together with an operation that combines …

36Genetic algorithm — A genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of… …
37Lp space — In mathematics, the Lp spaces are function spaces defined using a natural generalization of the p norm for finite dimensional vector spaces. They are sometimes called Lebesgue spaces, named after Henri Lebesgue (Dunford Schwartz 1958, III.3),… …
38Monad (category theory) — For the uses of monads in computer software, see monads in functional programming. In category theory, a branch of mathematics, a monad, Kleisli triple, or triple is an (endo )functor, together with two natural transformations. Monads are used in …
39Ridge detection — The ridges (or the ridge set) of a smooth function of two variables is a set of curves whose points are, loosely speaking, local maxima in at least one dimension. For a function of N variables, its ridges are a set of curves whose points are… …
