“…The result for all quasi-transitive graphs was conjectured by Benjamini and Schramm (1996) and first established by in the unimodular case, using a more complicated argument. Very recently, this result on ends was extended to the nonunimodular case by Haggstrom, Peres and Schonmann (1998). Their argument is based on different principles; in particular, it is not known in the nonunimodular case whether for p E (Pc, p), every infinite cluster must contain infinitely many encounter points.…”
