Fuzzy transformations and extremality of Gibbs measures for the Potts model on a Cayley tree

C Külske, UA Rozikov - Random Structures & Algorithms, 2017 - Wiley Online Library
We continue our study of the full set of translation‐invariant splitting Gibbs measures
(TISGMs, translation‐invariant tree‐indexed Markov chains) for the q‐state Potts model on a …

Luteinizing hormone-releasing hormone antagonists

G Mező, M Manea - Expert Opinion on Therapeutic Patents, 2009 - Taylor & Francis
Background: Luteinizing hormone-releasing hormone (LH-RH) plays a central role in the
vertebrate reproduction by regulating gonadal activity. Based on its binding to pituitary LH …

[HTML][HTML] The aggregate path coupling method for the Potts model on bipartite graph

JC Hernández, Y Kovchegov, PT Otto - Journal of Mathematical …, 2017 - pubs.aip.org
In this paper, we derive the large deviation principle for the Potts model on the complete
bipartite graph K n, n as n increases to infinity. Next, for the Potts model on K n, n, we …

Rapid mixing of Glauber dynamics of Gibbs ensembles via aggregate path coupling and large deviations methods

Y Kovchegov, PT Otto - Journal of Statistical Physics, 2015 - Springer
In this paper, we present a novel extension to the classical path coupling method to
statistical mechanical models which we refer to as aggregate path coupling. In conjunction …

Gibbsianness of locally thinned random fields

N Engler, B Jahnel, C Külske - arXiv preprint arXiv:2201.02651, 2022 - arxiv.org
We consider the locally thinned Bernoulli field on $\mathbb Z^ d $, which is the lattice
version of the Type-I Mat\'ern hardcore process in Euclidean space. It is given as the lattice …

Sharp thresholds for Gibbs–non-Gibbs transitions in the fuzzy Potts model with a Kac-type interaction

B Jahnel, C Külske - 2017 - projecteuclid.org
We investigate the Gibbs properties of the fuzzy Potts model on the d-dimensional torus with
Kac interaction. We use a variational approach for profiles inspired by that of Fernández …

Dynamical Gibbs–non-Gibbs Transitions in the Curie–Weiss Potts Model in the Regime

C Külske, D Meißner - Journal of Statistical Physics, 2021 - Springer
Abstract We consider the Curie–Weiss Potts model in zero external field under independent
symmetric spin-flip dynamics. We investigate dynamical Gibbs–non-Gibbs transitions for a …

[图书][B] Path coupling and aggregate path coupling

Y Kovchegov, PT Otto - 2018 - Springer
The coupling method is known as one of the few purely probabilistic techniques in
mathematics. In combination with other methods, the coupling has been an effective tool in …

[HTML][HTML] A class of non-ergodic probabilistic cellular automata with unique invariant measure and quasi-periodic orbit

B Jahnel, C Külske - Stochastic Processes and their Applications, 2015 - Elsevier
We provide an example of a discrete-time Markov process on the three-dimensional infinite
integer lattice with Z q-invariant Bernoulli-increments which has as local state space the …

[PDF][PDF] Potts models and stochastic dynamics

D Meißner - 2021 - hss-opus.ub.ruhr-uni-bochum.de
In this thesis we are investigating a time-evolved version of the symmetric mean-field Potts
model. It is our goal to understand the critical parameters (both temperature and time) for …
