Gibbs properties of the fuzzy Potts model on trees and in mean field
نویسنده
چکیده
We study Gibbs properties of the fuzzy Potts model in the mean field case (i.e. on a complete graph) and on trees. For the mean field case, a complete characterization of the set of temperatures for which non-Gibbsianness happens is given. The results for trees are somewhat less explicit, but we do show for general trees that nonGibbsianness of the fuzzy Potts model happens exactly for those temperatures where the underlying Potts model has multiple Gibbs measures.

A New Algorithm Based on Fuzzy Gibbs Random Fields for Image Segmentation
In this paper a new unsupervised segmentation algorithm based on Fuzzy Gibbs Random Field (FGRF) is proposed. This algorithm, named as FGS, can deal with fuzziness and randomness simultaneously. A Classical Gibbs Random Field (CGRF) servers as bridge between prior FGRF and original image. The FGRF is equivalent to CGRF when no fuzziness is considered; therefore, the FGRF is obviously a generali...
متن کاملA Mapping Relating Complex and Physical Temperatures in the 2D q-State Potts Model and Some Applications
We show an exact equivalence of the free energy of the q-state Potts antiferromagnet on a lattice Λ for the full temperature interval 0 ≤ T ≤ ∞ and the free energy of the q-state Potts model on the dual lattice for a semi-infinite interval of complex temperatures (CT). This implies the existence of two quite different types of CT singularities: the generic kind, which does not obey universality...
متن کاملIs the Fuzzy Potts Model Gibbsian?
– The fuzzy Potts model is obtained by looking at the Potts model with a pair of glasses that prevents distinguishing between some of the spin values. We show that the fuzzy Potts model on Z (d 2) is Gibbsian at high temperatures and non-Gibbsian at low temperatures. 2003 Published by Éditions scientifiques et médicales Elsevier SAS RÉSUMÉ. – Le modèle de Potts flou est obtenu en regardant le...
متن کاملFrom Trees to Galaxies: The Potts Model on a Random Surface
The matrix model of random surfaces with c = ∞ has recently been solved and found to be identical to a random surface coupled to a qstates Potts model with q = ∞. The mean field-like solution exhibits a novel type of tree structure. The natural question is, down to which— if any—finite values of c and q does this behavior persist? In this work we develop, for the Potts model, an expansion in th...
متن کاملGibbs States of Graphical Representations in the Potts Model with External Fields
We consider the ferromagnetic q-state Potts model, with each of the q spin values coupled to an external field. We also introduce a generalized random cluster model, which includes both the Potts model in arbitrary homogeneous external fields and the non-integer q random cluster model as special cases. We establish the FKG property, the finite energy condition, uniqueness of the infinite cluste...
