Pseudo-free energies and large deviations for non gibbsian FKG measures

SummaryA large deviation theorem for the invariant measures of translation invariant attractive interacting particle systems on {0, 1{Zd is proven. In this way a pseudo-free energy and pressure is defined. For ergodic systems the large deviations property holds with the usual scaling. The case of non ergodic systems is also discussed. A similar result holds for occupation times. The perturbation by an external field is treated.
