Abstract

We consider certain two-dimensional systems with self--dual points including uniform and disordered qq-state Potts models. For systems with continuous energy density (such as the disordered versions) it is established that the self--dual point exhibits critical behavior: Infinite susceptibility, vanishing magnetization and power law bounds for the decay of correlations.
