Soit Ω 2 un domaine borné de classe C 2+α ,0<α<1. On montre que si u est la solution maximale de Δu=4exp(2u), qui tend vers +∞ si (x,y)Ω, alors le rayon hyperbolique v=exp(−u) est de classe C2+α jusqu'au bord. La démonstration repose sur de nouvelles estimations de Schauder pour des équations fuchsiennes elliptiques.

Let Ω 2 be a bounded domain of class C 2+α ,0<α<1. We show that if u is the maximal solution of Δu=4exp(2u), which tends to +∞ as (x,y)Ω, then the hyperbolic radius v=exp(−u) is of class C2+α up to the boundary. The proof relies on new Schauder estimates for Fuchsian elliptic equations.
