Abstract

We develop an interpretation of the off-equilibrium dynamical solution of mean-field glassy models in terms of quasi-equilibrium concepts. We show that the relaxation of the "thermoremanent magnetization" follows a generalized version of the Onsager regression postulate of induced fluctuations. We then find the rationale to the equality between the {\it fluctuation-dissipation ratio} and the rate of growth of the configurational entropy close to the asymptotic state, found empirically in mean-field solutions.
