. For the solid-on-solid (SOS) model with spin values from the set of all integers on a Cayley tree we give gradient Gibbs measures (GGMs). Such a measure corresponds to a boundary law (which is an infinite-dimensional vector-valued function defined on vertices of the Cayley tree) satisfying an infinite system of functional equations. We give several concrete GGMs of boundary laws which are independent from vertices of the Cayley tree and (as an infinite-dimensional vector) have periodic, (non…

A non-linear second-order difference equation related to Gibbs measures of a SOS model

. For the SOS (solid-on-solid) model with an external field and with spin values from the set of all integers on a Cayley tree each (gradient) Gibbs measure corre-sponds to a boundary law (an

Gradient Gibbs measures of an SOS model with alternating magnetism on Cayley trees

. The work is devoted to gradient Gibbs measures (GGMs) of a SOS model with countable set Z of spin values and having alternating magnetism on Cayley trees. This model is defined by a nearest-neighbor

Fixed points of an infinite dimensional operator related to Gibbs measures

. We describe fixed points of an infinite dimensional non-linear operator related to a hard core (HC) model with a countable set N of spin values on the Cayley tree. This operator is defined by a



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.

Coexistence of localized Gibbs measures and delocalized gradient Gibbs measures on trees

We study gradient models for spins taking values in the integers (or an integer lattice), which interact via a general potential depending only on the differences of the spin values at neighboring

Random Surfaces: Large Deviations Principles and Gradient Gibbs Measure Classifications

A variational principle--characterizing gradient phases of a given slope as minimizers of the specific free energy--and an empirical measure large deviations principle (with a unique rate function minimizer) for random surfaces on mesh approximations of bounded domains are proved.

Non-uniqueness of Gibbs Measure for Models with Uncountable Set of Spin Values on a Cayley Tree

In this paper we construct several models with nearest-neighbor interactions and with the set [0,1] of spin values, on a Cayley tree of order k≥2. We prove that each of the constructed model has at

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
