抜粋

We present a proof of skeleton inequalities for ferromagnetic lattice spin systems with potential V(φ2) = (a/2)φ2 + Σn = 2M2n/(2n)!} φ2n (a real, λ2n ≥0) generalizing the Brydges-Fröhlich-Sokal and Bovier-Felder methods. As an application of the inequalities, we prove that, for sufficiently soft systems in d > 4 dimensions, critical exponents γ, α, and Δ4 take their mean-field values (i.e., γ = 1, α = 0, and Δ4 = 3/2).
