Propagation of order in the dilute antiferromagnetic three-state Potts model

A recent analysis of the propagation of order in a dilute 3-state Potts antiferromagnetic model on a triangular lattice at zero temperature by Adler et al. has shown the importance of nonlocality in the propagation of order. They study a linearized continuous version of this model, which can be mapped onto three independent percolation problems. They discuss the respective roles of nonlocality and nonlinearity, in particular in connection with central-force percolation
