. 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…

Periodic points of a $p$-adic operator and their $p$-adic Gibbs measures

. In this paper we investigate generalized Gibbs measure (GGM) for p -adic Hard-Core(HC) model with a countable set of spin values on a Cayley tree of order k ≥ 2. This model is defined by p -adic



The Potts Model with Countable Set of Spin Values on a Cayley Tree

We consider a nearest-neighbor Potts model, with countable spin values 0,1,..., and non zero external field, on a Cayley tree of order k (with k+1 neighbors). We study translation-invariant

Gradient Gibbs measures for the SOS model with countable values on a Cayley tree

We consider an SOS (solid-on-solid) model, with spin values from the set of all integers, on a Cayley tree of order k and are interested in translation-invariant gradient Gibbs measures (GGMs) of the

On the uniqueness of Gibbs measure in the Potts model on a Cayley tree with external field

The paper concerns the q-state Potts model (i.e. with spin values in ) on a Cayley tree of degree (i.e. with k  +  1 edges emanating from each vertex) in an external (possibly random) field. We

Gradient Gibbs measures and fuzzy transformations on trees

A construction for classes of tree-automorphism invariant gradient Gibbs measures in terms of mixtures of pinned measures, whose marginals to infinite paths on the tree are random walks in a q-periodic environment is provided.

Markov random fields and Markov chains on trees

We consider probability measures on a space S(^A) (where S and A are countable and the σ-field is the natural one) which are Markov random fields with respect to a given neighbour relation ~ on A. In

Fast mixing for independent sets, colorings, and other models on trees

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.

Graph Homomorphisms and Phase Transitions

We model physical systems with “hard constraints” by the space Hom(G, H) of homomorphisms from a locally finite graph G to a fixed finite constraint graph H. For any assignment ? of positive real

Phase transitions for a class of gradient fields

We consider gradient fields on $${\mathbb {Z}}^d$$ Z d for potentials V that can be expressed as $$\begin{aligned} e^{-V(x)}=pe^{-\frac{qx^2}{2}}+(1-p)e^{-\frac{x^2}{2}}. \end{aligned}$$ e - V ( x )

We consider models of gradient type, which are the densities of a collection of real-valued random variables $\phi :=\{\phi_x: x \in \Lambda\}$ given by $Z^{-1}\exp({-\sum\nolimits_{j \sim
