Graphical representations and cluster algorithms I. Discrete spin systems
Chayes, L.; Machta, J. - In: Physica A: Statistical Mechanics and its Applications 239 (1997) 4, pp. 542-601
Graphical representations similar to the FK representation are developed for a variety of spin-systems. In several cases, it is established that these representations have (FKG) monotonicity properties which enables characterization theorems for the uniqueness phase and the low-temperature phase...
