A new method to estimate the critical distortion of random fields

It was shown by C.M. Newman and G.A. Baker (1991) that the critical distortion d/sub c/ of the Ising model on z/sup k/ is related to the radius of convergence R of the classical Mayer series by d/sub c/=R/(1+R). An approach from statistical mechanics to estimate R as well as d/sub c/ by using the matrix representation of Mayer series is found.<
