We establish the existence of a weak solution u of the semilinear wave equation where a(t, x) is equal to 1 outside a compact set with respect to x and a non-linear term f k which satisfies |f k (u)| ≀ C |u | k . For some non-trapping time- periodic perturbations a(t, x), we obtain the long time ex
