3 Non-Gibbsianness for Majority-Rule Maps
, 1994
"... We show that decimation transformations applied to high-q Potts models result in non-Gibbsian measures even for temperatures higher than the transition temperature. We also show that majority transformations applied to the Ising model in a very strong field at low temperatures produce non-Gibbsian m ..."

2003) Analogues of non-Gibbsianness in joint measures of disordered mean field models
- J. Stat. Phys
"... It is known that the joint measures on the product of spin-space and disorder space are very often non-Gibbsian measures, for lattice systems with quenched disorder, at low temperature. Are there reflections of this non-Gibbsianness in the corresponding mean-field models? We study the continuity pro ..."

Robustness of the non-Gibbsian property: some examples
- J. Phys. A
, 1997
"... We discuss some examples of measures on lattice systems, which lack the property of being a Gibbs measure in a rather strong sense. 1 Introduction In recent years extensive research has been done on the occurrence of states (probability measures) on lattice systems which are not of Gibbsian type. ..."

Instability of Renormalization-Group Pathologies under decimation
, 1995
"... We investigate the stability and instability of pathologies of renormalization group transformations for lattice spin systems under decimation. In particular we show that, even if the original renormalization group transformation gives rise to a non Gibbsian measure, Gibbsiannes may be restored by a ..."

by applying an extra decimation trasformation. This fact is illustrated in details for the block spin transformation applied to the Ising model. We also discuss the case of another non-Gibbsian measure with nicely decaying correlations functions which remains non-Gibbsian after arbitrary decimation.
Gibbs vs. Non-Gibbs in the Equilibrium Ensemble Approach to Disordered Systems
, 2004
"... Abstract. We describe the salient ideas of the equilibrium ensemble approach to disordered systems, paying due attention to the appearance of non-Gibbsian measures. A canonical scheme of approximations — constrained annealing — is described and characterised in terms of a Gibbs ’ variational princip ..."
