Abstract

A tentative connection between the mean field theory and a variational version of the Migdal-Kadanoff renormalization technique is proposed for spin systems, through a direct calculation of the free energy. Some good results are obtained for the critical behaviour of the Ising and the Potts models for low dimensions.
