N2 - Let G(x) be a C0 function such that G(x) ≤ K x p for x ≤ c, for constants K, c > 0. We consider spherically symmetric solutions of □gφ = G(φ) where g is a Schwarzschild or more generally a Reissner-Nordström metric, and such that φ and ∇φ are compactly supported on a complete Cauchy surface. It is proven that for p > 4, such solutions do not blow up in the domain of outer communications, provided the initial data are small. Moreover, φ ≤ C(max{ν, 1})-1, where ν denotes an Eddington-Finkelstein advanced time coordinate.
