Abstract. In this paper we consider countable state p-adic Potts model on the Cayley tree. A construction of p-adic Gibbs measures which depends on weights λ is given, and an investigation of such measures is reduced to examination of an infinite-dimensional recursion equation. Studying the derived equation under some condition concerning weights, we prove the absence of a phase transition. Note that the condition does not depend on values of the prime p, and an analogues fact is not true when the number of spins is finite. For homogeneous model it is shown that the recursive equation has only one solution under that condition on weights. This means that there is only one p-adic Gibbs measure µ λ . The boundedness of the measure is also established. Moreover, continuous dependence of the measure µ λ on λ is proved. At the end we formulate one limit theorem for µ λ .Mathematics Subject Classification: 46S10, 82B26, 12J12, 39A70, 47H10, 60K35.
