In mathematics, a covering system (also called a complete residue system) is a collection of finitely many residue classes whose union contains every integer. (en) En mathématiques, un système couvrant est un recouvrement fini de l'ensemble ℤ des entiers relatifs par des classes résiduelles, c'est-à-dire un ensemble fini de classes dont la réunion est égale à ℤ. Cette notion a été introduite par Paul Erdős en 1950. (fr) Покрывающая система (или полная покрывающая система) — это набор конечного числа классов вычетов , объединение которых покрывает все целые числа. (ru) |
