Disordered Potts model

For the identification of the topological state of the knot we use the Kauffman algebraic invariant K(A), which is the Laurent polynomial in A variable. We have shown the Kauffman invariant to be equal to the partition function of some special disordered Potts model [3, 4]. The number of equivalent states, and the nearest neighbor interaction constant, J /, are defined as follows ...
