Supremum over inverse image of functions in the Bloch space
[La borne supérieure de l'image inverse de fonctions dans l'espace de Bloch]
Comptes Rendus. Mathématique, Tome 344 (2007) no. 5, pp. 291-294.

Nous démontrerons que pour certaines classes de fonctions f dans l'espace α-Bloch Bα et telles que f(0)=0, la norme Bα s'obtient comme la borne supérieure sur f−1(Σε), où Σε={z:|argz|<ε}.

We will prove that for certain classes of functions f in the α-Bloch space Bα such that f(0)=0, the Bα norm is obtained taking supremum over f−1(Σε), where Σε={z:|argz|<ε}.
