The authors study the two-dimensional nonlinear O(N) sigma model from Wilson Renormalization Group viewpoint. They show the existence of the renormalized trajectory in perturbation theory in the effective charge. This model is also useful in the small field analysis of the rigorous renormalization group construction of the continuum theory.
