The Thompson’s group F is one of the most famous and most important groups related to many areas of mathematics (see the survey [3]). The question about amenability of this group remains open for more than 50 years despite many attempts to solve it. By a remarkable Kesten’s criterion of amenability a group G is amenable if and only if 1 belongs to the spectrum of the Markov operator associated to a symmetric random walk on G. This criterion also holds for graphs of uniformly bounded degree (see…

On spectra and spectral measures of Schreier and Cayley graphs
We are interested in various aspects of spectral rigidity of Cayley and Schreier graphs of finitely generated groups. For each pair of integers $d\geq 2$ and $m \ge 1$, we consider an uncountable
Some Graphs Related to Thompson’s Group F
The Schreier graphs of Thompson’s group F with respect to the stabilizer of 1/2 and generators x 0 and x 1 , and of its unitary representation in L 2 ([0, 1]) induced by the standard action on the
Schreier graphs of actions of Thompson’s group $$F$$F on the unit interval and on the Cantor set
Schreier graphs of the actions of Thompson’s group $$F$$F on the orbits of all points of the unit interval and of the Cantor set with respect to the standard generating set $$\{x_0,x_1\}$${x0,x1} are
Spectra of Schreier graphs of Grigorchuk’s group and Schroedinger operators with aperiodic order
We study spectral properties of the Laplacians on Schreier graphs arising from Grigorchuk’s group acting on the boundary of the infinite binary tree. We establish a connection between the action of G
On the Spectrum of Hecke Type Operators related to some Fractal Groups
We give the first example of a connected 4-regular graph whose Laplace operator's spectrum is a Cantor set, as well as several other computations of spectra following a common ``finite
Thompson's group $F$ is not Liouville
We prove that random walks on Thompson's group $F$ driven by strictly non-degenerate finitely supported probability measures $\mu$ have a non-trivial Poisson boundary. The proof consists in an
Amenability and paradoxical decompositions for pseudogroups and for discrete metric spaces
This is an expostion of various aspects of amenability and paradoxical decompositions for groups, group actions and metric spaces. First, we review the formalism of pseudogroups, which is well
Self-similar groups, operator algebras and Schur complement
In the first part of the article we introduce $C$*-algebras associated to self-similar groups and study their properties and relations to known algebras. The algebras are constructed as subalgebras
Spectral distribution and L2-isoperimetric profile of Laplace operators on groups
We give a formula relating the L2-isoperimetric profile to the spectral distribution of a Laplace operator on a finitely generated group Γ. We prove the asymptotic stability of the spectral
On spectra of Koopman, groupoid and quasi-regular representations
In this paper we investigate relations between Koopman, groupoid and quasi-regular representations of countable groups. We show that for an ergodic measure class preserving action of a countable
