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

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 Cayley tree. In our previous work (Külske et al., J Stat Phys 156 (2014), 189–200) we gave a full description of the TIS... View More
