‖ A ‖ désignera le cardinal de A. Soient T une théorie complète du premier ordre dans un langage dénombrable, M un modèle de T, X un sous-ensemble de M; soit T(X) l'ensemble des formules closes à paramètres dans X satisfaites par M; on appelle n-type de T sur X un ensemble consistant avec T(X) et maximal de formules à paramètres dans X à n variables libres.
