The instability which arises in current mean-field theories of spin-glasses is removed, within the replica method, by breaking the symmetry between replicas. For the Sherrington-Kirkpatrick (SK) model the spin-glass order parameter has the expansion q=t+t^2+O (t^3) (t=1-T{T₂}), which differs at O (t^2) from that given by Sk.
Bray et al. (Mon,) studied this question.
