The variational-principle conjecture for finite domino configurations

About 26 years old · traced to

Consider a sequence of finite regions converging to a fixed shape, and let (s,t)(s,t) be the tilt given by the variational principle wherever that tilt is defined. Let μs,t\mu_{s,t} be the associated measure on plane domino tilings. Finite-region configuration conjecture. In the thermodynamic limit for a sequence of finite regions converging to a fixed shape, the probability of seeing any colored configuration of dominos is given by the measure μs,t\mu_{s,t}, wherever the tilt (s,t)(s,t) given by the variational principle is defined and satisfies ∣s∣+∣t∣<2|s|+|t|<2. This is presented as a further claim conditional on the torus-to-plane convergence conjecture and is described in the source as an open problem connecting the variational principle to local configuration probabilities.
