| Abstract: | A migdal-Kadanoff transformation is improved by using the mean-field approximation to find the relation between the coupling constants of the restructured lattice and the on ginal one.Calculations of the critical coupling and exponents for the Ising model showed much improvement, even for small clusters, compared with the results of MK calculations. |
