| الوصف: | We establish results connecting the uniform Liouville property of group actions on the classes of a countable Borel equivalence relation with amenability of this equivalence relation. We also study extensions of Kesten's theorem to certain classes of topological groups and prove a version of this theorem for amenable SIN groups. Furthermore, we discuss relationship between generalizations of Kesten's theorem and anticoncentration inequalities for the inverted orbits of random walks on the classes of an amenable equivalence relation. This allows us to construct an amenable Polish group that does not satisfy the limit conditions in combinatorial extensions of Kesten's theorem. Comment: Significant changes in exposition, results updated, answered one of the questions from the first version |
