摘要：

Consider the statistical mechanics model on the ν-dimensional lattice with nearest-neighbor interaction and single spin distribution given by λ(q2-1)2, λ>0. The strong-coupling region λ→â is studied, and it is shown that in the high-temperature region there is an expansion of this model in powers of λ-1 which is asymptotic to the Ising model (λ=â) to any order. © 1979 The American Physical Society.
