Abstract
We study the N --> 0 limit of the O(N) Gross-Neveu model in the framew ork of the massless form-factor approach. This model is related to the continuum limit of the Ising model with random bonds via the replica method. We discuss how this method may be useful in calculating correl ation functions of physical operators. The identification of non-pertu rbative fixed points of the O(N) Gross-Neveu model is pursued by its m apping to a Wess-Zumino-Witten model.
