Some remarks on Q-algebras
Annales de l'Institut Fourier, Tome 22 (1972) no. 4, pp. 1-11.

On fait une étude des algèbres qui sont des quotients des algèbres uniformes et on démontre que cette classe est stable par interpolation. On démontre en particulier que le p , (1p) appartiennent à cette classe et que A n =L 1 (Z;1+|n| α ) appartient à cette classe si et seulement si α>1/2.

We study Banach algebras that are quotients of uniform algebras and we show in particular that the class is stable by interpolation. We also show that p , (1p) are Q algebras and that A n =L 1 (Z;1+|n| α ) is a Q-algebra if and only if α>1/2.
