Ising models on hyperbolic graphs

  • C. Chris Wu
Short Communications

Abstract

We consider Ising models on a hyperbolic graph which, loosely speaking, is a discretization of the hyperbolic planeH2 in the same sense asZd is a discretization ofRd. We prove that the models exhibit multiple phase transitions. Analogous results for Potts models can be obtained in the same way.
