QUE SIGNIFIE ORDINAL NUMBER EN ANGLAIS
Nombre ordinal
Dans la théorie des ensembles, un nombre ordinal, ou simplement ordinal, est le type d'ordre d'un ensemble bien ordonné. Ils sont généralement identifiés avec des ensembles héréditairement transitifs. Les ordinals sont une extension des nombres naturels différents des entiers et des cardinaux. Comme d'autres types de nombres, les ordinales peuvent être ajoutés, multipliés et exponentiels. Les ordines ont été introduites par Georg Cantor en 1883 pour accueillir des séquences infinies et pour classer des ensembles avec certains types de structures d'ordre sur eux. Il les a dérivés par accident en travaillant sur un problème concernant les séries trigonométriques. Deux ensembles S et S 'ont la même cardinalité s'il existe une bijection entre eux (c'est-à-dire qu'il existe une fonction f à la fois injective et surjective, c'est-à-dire cartographie chaque élément x de S à un élément unique y = f (x) De S 'et chaque élément y de S' provient exactement d'un tel élément x de S).
définition de ordinal number dans le dictionnaire anglais
