Abstract

We consider a nearest-neighbor inhomogeneous p-adic Potts (with q ≥ 2 spin values) model on the Cayley tree of order k ≥ 1. The inhomogeneity means that the interaction Jxy couplings depend on nearest-neighbors points x, y of the Cayley tree. We study (p-adic) Gibbs measures of the model. We show that (i) if q ∉ pℕ then there is unique Gibbs measure for any k ≥ 1 and ∀ Jxy with |Jxy| < p -1/(p-1). (ii) For q ∈ pℕ, p ≥ 3 one can choose J xy and k ≥ l such that there exist at least two Gibbs measures which are translation-invariant.
