Critical Percolation on any Nonamenable Group has no Infinite Clusters

Abstract: We show that independent percolation on any Cayley graph of a nonamenable group has no infinite components at the critical parameter. This result was obtained by the present authors earlier as a eorollary ofa general study of group-invariant percolation. The goal here is to present a simpler self-contained proof that easily extends to quasi-transitive graphs with a unimodular automorphism group. The key tool is II "mass-transport" method, which is a technique of averaging in nonamenable settings.

“…The Mass-Transport Principle in itself is not especially deep or difficult. Rather, in the words of BLPS [10]' "the creative element in applying the mass-transport method is to make a judicious choice of the transport function m( u, v, w)". We will see some examples in this section and the next.…”
