DAMAGE SPREADING IN THE (N-ALPHA,N-BETA) MODEL - EXACT RESULTS

The (N-alpha, N-beta) model is investigated within the damage-spreadin g framework. Exact relations involving thermodynamic quantities (order parameters and correlation functions) and conveniently defined combin ations of damages are obtained, which are valid for any regular (trans lationally invariant) lattice. The corresponding existing results for particular cases of the model, e.g., Ising, Potts, Ashkin-Teller and d iscrete N-vector models, are all recovered by the present relations.
