The operator product expansion converges in massless -theory
Jan Holland, Stefan Hollands, Christoph Kopper
It has been shown recently that the mathematical status of the operator product expansion (OPE) is better than was expected before: namely considering massive Euclidean -theor…
The operator product expansion converges in perturbative field theory
Stefan Hollands, Christoph Kopper
We show, within the framework of the Euclidean -quantum field theory in four dimensions, that the Wilson operator product expansion (OPE) is not only an asymptotic expansion a…
Large Momentum bounds from Flow Equations
Christoph Kopper, Frederic Meunier
We analyse the large momentum behaviour of 4-dimensional massive euclidean Phi-4-theory using the flow equations of Wilson's renormalization group. The flow equations give access t…
Temperature Independent Renormalization of Finite Temperature Field Theory
Christoph Kopper, Volkhard F. Müller, Thomas Reisz
We analyse 4-dimensional massive $\vp^4$ theory at finite temperature T in the imaginary-time formalism. We present a rigorous proof that this quantum field theory is renormalizabl…
Renormalization Proof for Spontaneously broken Yang-Mills Theory with Flow Equations
Ch. Kopper, V. F. Mueller
The proof given in the paper was incomplete due to an omission in the proof of Lemma 2. A corrected and improved version of the paper is in arXiv:0902.2486.
