Scaling laws for ising models near Tc

A model for describing the behavior of Ising models very near $T_c$ is introduced. The description is based upon dividing the Ising model into cells which are microscopically large but much smaller than the coherence length and then using the total magnetization within each cell as a collective variable. The resulting calculation serves as a partial justification for Ifidom's conjecture about the homogeneity of the free energy and at the same time gives his result $s\nu \prime =\mathrm{\gamma }\prime +2\mathrm{\beta }$.
