Abstract: For Ising models with general interactions correlation-function identities of the form ΣBλB〈σB〉〈σBσA〉 = 0 are studied. It is shown that each identity of this form is equivalent to a set of special identities, in which the coefficients λB take only the values -1,0,1. A necessary and sufficient condition for the validity of such a special identity is derived.
