Abstract: We obtain convergent multi-scale expansions for the one-and two-point correlation functions of the low temperature lattice classical N– vector spin model in d≥ 3 dimensions, N≥ 2. The Gibbs factor is taken as where , , , are large and 0 〈 v≤ 1. In the thermodynamic and limits, with h=e 1, and Δ≡∂★∂, the expansion gives (spontaneous magnetization), , (Goldstone Bosons), , and , where , for some ρ 〉 0, and c 0 is aprecisely determined constant.
