More correlation inequalities for a class of even ferromagnets
Tóm tắt
Rigorous correlation inequalities are presented for a class of even ferromagnets, which includes the spin-1/2 Ising model and scalar ϕ4 models. One of them leads to an extension of the Glimm and Jaffe uniform upper bound on the ϕ4 renormalized coupling constant into the nonsymmetric regime.
