Phase transitions on lattice graphs

Author: G. Grimmett (University of Cambridge)


We explain the random-cluster (or FK) representation of the classical Potts/Ising models, when the underlying graph is a lattice. There is a continuum version of the random-cluster model that may be used to study the quantum Ising model with transverse field. A selection of open problems will be included.
