| Abstract: | The purpose of this paper is to investigate the renormalization group equations for massless models with two couplings and vanishing lowest order contribution of the β-function. It is shown that in this case the renormalization group equations can be reduced to others of Briot-Bouquet type. This observation permits to study in a simple and obvious manner the stability and asymptotic behaviour of solutions in the weak coupling limit. |
