Nous montrons qu’un théorème de Rudin, concernant la somme des sous-espaces fermés dans un espace de Banach, a une réciproque. Au moyen d’un exemple nous montrons que ce résultat a le caractère d’être le meilleur possible.
We show that a theorem of Rudin, concerning the sum of closed subspaces in a Banach space, has a converse. By means of an example we show that the result is in the nature of best possible.
