Variational principle for the distribution function of the effective field for the random Ising model in the Bethe approximation
Description
The random Ising model is studied in the pair approximation of the cluster variation method. It is shown that the distribution function of the effective field is determined either by a reducibility condition of the distribution function of two sites to that of one site or by a stationarity condition of the averaged free energy.
