Let be an additive function on a ring of sets, with values in a commutative Hausdorff topological group, and let be an ideal of . Conditions are given under which can be represented as the sum of two additive functions, one essentially supported on , the other vanishing on . The result is used to obtain two Lebesgue-type decomposition theorems. Other applications and the corresponding theory for outer measures are also indicated.
Soit une fonction additive définie sur un clan à valeurs dans un groupe topologique commutatif séparé et soit un idéal de . On donne des conditions suffisantes pour que soit la somme de deux fonctions additives, l’une essentiellement portée sur , l’autre nulle sur . Ce résultat est utilisé pour obtenir deux décompositions de Lebesgue. On indique aussi d’autres applications ainsi que la théorie correspondante pour les mesures extérieures.
