Abstract. We develop a resummed high-temperature expansion for lattice spin systems
with long range interactions, in models where the free energy is not, in
general, analytic. We establish uniqueness of the Gibbs state and
exponential decay of the correlation functions. Then, we apply this
expansion to the Perron-Frobenius operator of weakly coupled map lattices.
