Abstract
We show within the Wilson renormalization group framework how the flow equation method can be used to prove the perturbative renormalizabili ty of relativistic massive Phi(4)(4). Furthermore we prove the regular ity of the renormalized relativistic one-particle irreducible n-point Green functions in the region predicted by axiomatic quantum field the ory which ensures that physical renormalization conditions for the two -point function can be imposed.
