Abstract. We establish an inequality between the critical percolation value
of frustraded random cluster models and that of an unfrustrated model
where the free occupation probabilities of some bonds are strictly
decreased. Using the FK representation this gives an inequality
between the critical temperatures
of the corresponding spin models. In this way
we can prove a strict inequality
between critical temperatures for symmetry breaking of some frustrated
Ising models and the corresponding ferromagnetic models.
