Concentration inequalities for random fields via coupling
J. -R. Chazottes, P. Collet, C. Kuelske +1
We present a new and simple approach to concentration inequalities for functions around their expectation with respect to non-product measures, i.e., for dependent random variables…
Loss without recovery of Gibbsianness during diffusion of continuous spins
C. Kuelske, F. Redig
We consider a specific continuous-spin Gibbs distribution for a double-well potential that allows for ferromagnetic ordering. We study the time-evolution of this initial…
How non-Gibbsianness helps a metastable Morita minimizer to provide a stable free energy
Christof Kuelske
We analyze a simple approximation scheme based on the Morita-approach for the example of the mean field random field Ising model where it is claimed to be exact in some of the phys…
Gibbs properties of the fuzzy Potts model on trees and in mean field
Olle Haeggstroem, Christof Kuelske
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…
