A short introduction on topological properties of (regular and random) geometrical sets is presented along with some recent results concerning the behaviour of the Euler-PoincareΔ haracteristic with respect to the (Fortuin-Kasteleyn) random cluster measure.

β¦ Synopsis
In this talk, we review elements of knot theory and knot invariants and their connections with exactly solvable models in statistical mechanics. The generation of knot invariants from vertex models, interaction-round-face models, and spin models with two-spin interactions is elucidated [I]. The example of generating a new invariant from the chiral Potts model with the use of a generalized Gaussian summation identity is given [2,3]; a table of invariants for links with up to eight crossings can be found in [3].

We generalize a result of Scharlemann and Thompson (1989) to obtain a relation between the Thurston norms of links related by "skein moves", in irreducible homology 3-spheres. Then we apply this result to the study of "skein trees" of links and we formulate an obstruction to the convergence of the H
It is shown that equilibrium states of classical systems of point particles are translation invariant whenever they have integrable clustering. Equilibrium states are defined by correlation functions obeying the BBGKY hierarchy. The result holds for two-body forces which may have locally integrable
