http://www.wiese.itp.unibe.ch/theses/nyfeler_master.pdf WebSince we focus on the Ising model, we will assume that q= 2 unless otherwise stated. We will only work in the sub-critical regimes where the uniqueness of the random cluster model µ= qω(γ) ⋉η(p) is well established [20]. It is well-known (see [20]) that the random cluster models satisfy a stochastic domination relation, so that
