Solution globale d'une équation non linéaire sur une variété hyperbolique
The authors prove the existence of a global and unique solution of the Cauchy problem for the equation \(\square_ gu+au+bu^ 3=0\) on a globally hyperbolic 4-dimensional manifold (V,g) when the Cauchy data are given on a space-like section and a,b are given positive functions on V.
