L. Pastur et al., THE REPLICA-SYMMETRICAL SOLUTION WITHOUT REPLICA TRICK FOR THE HOPFIELD MODEL, Journal of statistical physics, 74(5-6), 1994, pp. 1161-1183
We derive the saddle-point equations for the order parameters of the H
opfield model in the case of replica symmetry without using the replic
a trick, but assuming that the Edwards-Anderson parameter is a self-av
eraging quantity.
