Abstract

We consider a d-dimensional Ising spin glass and construct lower bounds for the mean free energy density which, in general, improve the classical lower bounds given by the annealed free energy density. The bounds are achieved by introducing generalized finite-volume free energy densities. The large-deviations aspects of the problem are displayed and examples discussed.
