Webevant to the mixing rate of the Glauber dynamics. We ﬁrst describe Glauber dynamics for proper coloring. Let be a graph. A coloring of with colors is proper if no two adjacent vertices are assigned the same color. Glauber dynamics are the following Markov chain on the set of proper colorings: Let $#&% '(% be a proper coloring. Deﬁne in the ... WebThis paper establishes a well-known conjecture that the Glauber dynamics converges very quickly to its stationary distribution in the tree uniqueness region, i.e., decay of correlations region. The Glauber dynamics is the quintessential example of a local Markov chain, and its convergence rate is of great interest due to its sim- the nansei islands
