Abstract

The Glauber dynamics of the Little-Hopfield model is studied analytically with the help of path-integrals recently introduced by Sommers. The results of Amit, Gutfreund and Sompolinsky concerning the statics of the Little-Hopfield model near saturation are dynamically verified. Their replica-symmetric solution corresponds exactly to the self-consistency equations of the long-time limits of some time-dependent functions emerging in our dynamical treatment. We also found their generalized Almeida-Thouless line where the solution becomes unstable. The time-dependent evolution of the macroscopic overlaps for a finite number of stored patterns is investigated and the problems arising for an infinite number of them are indicated.
