Abstract

We consider a nearest-neighbor p-adic Potts (with q ≥ 2 spin values and coupling constant J ε ℚp) model on the Cayley tree of order k ≥ 1. It is proved that a phase transition occurs at k = 2, q ε pℕ> and p ≥ 3 (resp. q ε 22ℕ, p = 2). It is established that for p -adic Potts model at k ≥ 3 a phase transition may occur only at q ε p ℕ if p ≥ 3 and q ε 22ℕ if p = 2.
