Interaction Flip Identities for non Centered Spin Glasses    [PDF]

Pierluigi Contucci, Cristian Giardina', Claudio Giberti
We consider spin glass models with non-centered interactions and investigate the effect, on the random free energies, of flipping the interaction in a subregion of the entire volume. A fluctuation bound obtained by martingale methods produces, with the help of integration by parts technique, a family of polynomial identities involving overlaps and magnetizations.
