Functional equations for the Potts model with competing interactions on a Cayley tree
G. I. Botirov – Institute of Mathematics, National University of Uzbekistan; email@example.com
In this paper, we consider an infinite system of functional equations for the Potts model with competing interactions of radius r = 2 and countable spin values 0, 1, . . . . . , and non-zero-filled, on a Cayley tree of order two. We describe conditions on hx guaranteeing compatibility of distributions μ(n)(σ(n)).
Keywords: Cayley tree, Potts model, Gibbs measures, functional equations.
