Consider an intermittent map f(kappa) : [0,1] -> [0,1] and a Holder continuous potential phi : [0,1] -> R. We show that phi is stochastic for f(......

A graph Gamma is called (G, s)-arc-transitive if G <= Aut(Gamma) is transitive on the set of vertices of Gamma and the set of s-arcs of Gamma, wher......
