Abstract
The free energy of the Husimi–Temperley model under a random field is obtained in terms of the n‐replica method. The interchangeability of various limits such as the thermodynamic limit, the limit n→0 where n is the number of replicas, etc., is justified on the usage of the n‐replica method in the course of the evaluation of the free energy. A tricritical point is found for the model under the random field which takes on two values σ and −σ with equal probability.Keywords
