Actions of frieze groups on inverse limits of polynomial rings
Elitza Hristova, Bogdan Stankov
In the spirit of the action of the symmetric group on the ring of polynomials in variables, we consider the actions of the seven frieze groups on rings of formal infinite linea…
Coulhon Saloff-Coste isoperimetric inequalities for finitely generated groups
Christophe Pittet, Bogdan Stankov
We prove an inequality, valid on any finitely generated group with a fixed finite symmetric generating set, involving the growth of successive balls, and the average length of an e…
Exact descriptions of Følner functions and sets on wreath products and Baumslag-Solitar groups
Bogdan Stankov
We calculate the exact values of the Følner function of the lamplighter group for the standard generating set. More generally,…
Convergence towards the end space for random walks on Schreier graphs
Bogdan Stankov
We consider a transitive action of a finitely generated group and the Schreier graph defined by this action for some fixed generating set. For a probability measure on…
Non-triviality of the Poisson boundary of random walks on the group of Monod
Bogdan Stankov
We give sufficient conditions for the non-triviality of the Poisson boundary of random walks on and its subgroups. The group is the group of piecewi…
