Dynamical Gibbs-non-Gibbs transitions in the Curie-Weiss Potts model in the regime \(\beta<3\) (Q2046518)

In the present paper, the authors investigate the Curie-Weiss Potts model in zero external field under independent symmetric spin-flip dynamics. Dynamical Gibbs-non-Gibbs transitions are studied for a range of initial inverse temperatures \(\beta<3\), which covers the phase transition point \(\beta=4 \log 2\). It is established that finitely many types of trajectories of bad empirical measures appear, depending on the parameter \(\beta\), with a possibility of re-entrance into the Gibbsian regime.
