Recurrence of tangent-vector graphs for leaf-constructed measures

About 6 years old · traced to

Let TT be a triangulation, let xx be a tangent vector on TT, and let GxG^x denote the corresponding graph of discrete tangent vectors. Suppose that GxG^x is recurrent and that the measure νx\nu_x exists. Recurrence conjecture. The graph GyG^y is recurrent for νx\nu_x-almost every yy. If true, this would imply amenability of G^\hat{G} equipped with the transverse measure νx\nu_x constructed under these conditions; the analogous amenability result is already proved for measures constructed as limits of measures on spheres.
