@inproceedings{Khakimov2022GibbsMF, title={Gibbs measures for HC-model with a countable set of spin values on a Cayley tree}, author={R. M. Khakimov and M. T. Makhammadaliev and Utkir A. Rozikov}, year={2022} }
. In this paper, we study the HC-model with a countable set Z of spin values on a Cayley tree of order k ≥ 2 . This model is defined by a countable set of parameters (that is, the activity function λ i > 0 , i ∈ Z ). A functional equation is obtained that provides the consistency condition for finite-dimensional Gibbs distributions. Analyzing this equation, the following results are obtained: - Let Λ = ∑ i λ i . For Λ = +∞ there are no translation-invariant Gibbs measures (TIGM) and no two…

This work generalizes a framework, developed in the recent paper [18] in the context of the Ising model, for establishing mixing time O(n log n), which ties this property closely to phase transitions in the underlying model.
