Abstract
We perform numerical estimates for the q-state Potts model on a k-order Cayley tree. Külske, Rozikov and Khakimov explicitly calculated up to 2^q − 1 TISGMs (Translation Invariant Splitting Gibbs Measures) for the binary tree (k = 2), without an external field (α = 0). We extend these results numerically for k > 2 and α ≠ 0. We conjecture that for α ≥ k − 1 the model has niqueness. Additionally, decay of memory is proved for a Potts-type model on a Bayesian network with up to two parents and a counterexample is given for a more general case.
