We treat as prototype for four-dimensional nonlinear quantum field theories the g(p4 theory in the Einstein Universe E = R' x S3. The underlying free system is defined by the Klein-Gordon equation in E. We show rigorously, without the intervention of any cutoffs or perturbative renormalizations, tha
