All-order uniform momentum bounds for the massless phi^4 theory in four dimensional Euclidean space
Riccardo Guida, Christoph Kopper
A panoramic overview is given, of a theorem [1] establishing physical and uniform bounds on the Fourier-transformed Schwinger functions of a massless phi^4 theory in four Euclidean…
Continuity of the four-point function of massive -theory above threshold
Christoph Kopper
In this paper we prove that the four-point function of massive $\vp_4^4$-theory is continuous as a function of its independent external momenta when posing the renormalization cond…
Renormalization Proof for Massive phi_4^4 Theory on Riemannian Manifolds
Christoph Kopper, Volkhard F. Müller
In this paper we present an inductive renormalizability proof for massive $\vp_4^4$ theory on Riemannian manifolds, based on the Wegner-Wilson flow equations of the Wilson renormal…
Perturbative Renormalization with Flow Equations in Minkowski Space
Georg Keller, Christoph Kopper, Clemens Schophaus
We show within the Wilson renormalization group framework how the flow equation method can be used to prove the perturbative renormalizability of a relativistic massive selfinterac…
