Abstract For a one-dimensional array ofS N−1 spins (N ⩾ 2) with isotropic pair interactions (and more general systems) with J(j−i) obeying supn[n−1∑ 1 n j 2|J(j)|]〈∞, we prove that every equilibrium state is invariant under the natural action ofSO(N). In particular, there is no long-range order of the conventional type. Included is the caseJ(n)=n −2.
