On démontre que dans l’algèbre de Fréchet C(B) il y a exactement trois sous-algèbres Y qui sont fermées, qui contiennent des fonctions non constantes, et qui sont invariantes dans le sens suivant : f∘Ψ∈Y lorsque f∈Y et Ψ est une application biholomorphe de la boule unité ouverte B de C n sur B. Ce sont (i) l’algèbre des fonctions holomorphes dans B, (ii) l’algèbre des fonctions f dont les conjuguées f ¯ sont holomorphes, (iii) C(B).

It is proved that the Fréchet algebra C(B) has exactly three closed subalgebras Y which contain nonconstant functions and which are invariant, in the sense that f∘Ψ∈Y whenever f∈Y and Ψ is a biholomorphic map of the open unit ball B of C n onto B. One of these consists of the holomorphic functions in B, the second consists of those whose complex conjugates are holomorphic, and the third is C(B).
