Abstract
We study the mixing time of the symmetric beta-binomial splitting process on finite weighted connected graphs G = (V,E,{re}e∈E) with vertex set V , edge set E and positive edge-weights re > 0 for e ∈ E. This is an interacting particle system with a fixed number of particles that updates through vertex-pairwise interactions which redistribute particles. We show that the mixing time of this process can be upper-bounded in terms of the maximal expected meeting time of two independent random walks on G. Our techniques involve using a process similar to the chameleon process invented in [18] to bound the mixing time of the exclusion process.
