Abstract

Convergence of the mean field equations is analyzed for the Ising model with a nonhomogeneous external field. When β is small, the equations are a contraction mapping and thereby convergent. When β is large, however, they can be noncontracting and in this case, contraction is restored by a slight modification of the equations
