Abstract
Differential renormalization equation for the -state Potts model are proposed, and the critical behavior of the model near discussed. The equations give rise to critical and tricritical fixed points which merge at when a dilution field becomes marginal, to an essential singularity in the latent heat as a function of , in accordance with the exact result of Baxter, and, for , to a logarithm correction to the power-law behavior of the free energy as a function of .
