Uniqueness of the Gibbs state of the BEG model in the disordered region of parameters

Uniqueness of the Gibbs state of the BEG model in the disordered region of parameters

We show that the d -dimensional Blume–Emery–Griffiths model has a unique Gibbs state, for all temperatures, in some portion of disordered region of parameters, ruling out the possibility of a reentrant behavior in the same.
