The power series coherent anomaly method is applied to study the critical properties of a classical Heisenberg model. The values of true critical temperature Tc∗ are obtained. Using these results the estimation of critical exponent γ for the zero-field static susceptibility has been made. The...

The purpose of this paper is the application of a usual method of statistical mechanics—the renormalization based on Wilson's recursive relations—in order to study the critical behavior of a social index, namely the live births per 1000 population. The drastic decreases of this index on...
