Everyone is welcome to attend the next N&O seminar with Ferenc Bencs with the title "A uniqueness result about Gibbs measures".
The talk will take place in L120 at CWI. For more information, please contact Willem Feijen (willem.feijen at cwi.nl), Samarth Tiwari (samarth.tiwari at cwi.nl) or Sven Polak (sven.polak at cwi.nl).
Abstract: In the talk we will investigate a question related to statistical physics. The Potts-model is a coloring model and we are interested in when antiferromagnetic parametrization of this model has a unique probability measure on the infinite regular tree. We will confirm that for any number of colors q if the interaction is at least 1-w/q and the degree is large enough, then there exists only one unique measure.
