It is related to the semidirect product construction for groups. (Roughly speaking, crossed product is the expected structure for a group ring of a semidirect product group. Therefore crossed products have a ring theory aspect also. This article concentrates on an important case, where they appear in functional analysis.)where they appear in functional analysis.)

Cette construction de base est reliée à celle du produit semi-direct, groupe résultant de l'action d'un groupe sur un autre. Voici un petit exemple: 13/65 pour mettre sa sur 100: 13/65 ?/100 donc 13x100=1300 et 1300 divisé par 65 = 20 o 20%.
