Stochastic homogenization of horospheric tree products
Vadim A. Kaimanovich, Florian Sobieczky · Advanced studies in pure mathematics · 2019
We construct measures invariant with respect to equivalence relations which are graphed by horospheric products of trees. The construction is based on using conformal systems of boundary measures on treed equivalence relations. The existence of such an invariant measure allows us to establish amenability of horospheric products of random trees.
