On the space of subgroups of Baumslag-Solitar groups II: High transitivity
Damien Gaboriau, François Le Maître, Yves Stalder
We continue our study of the perfect kernel of the space of transitive actions of Baumslag-Solitar groups by investigating high transitivity. We show that actions of finite phenoty…
On homology torsion growth
Miklos Abert, Nicolas Bergeron, Mikolaj Fraczyk +1
We prove new vanishing results on the growth of higher torsion homologies for suitable arithmetic lattices, Artin groups and mapping class groups. The growth is understood along Fa…
Sofic entropy, after Lewis Bowen, David Kerr and Hanfeng Li
Damien Gaboriau
The entropy in dynamical systems was introduced by A. Kolmogorov. Initially dedicated to iterations of one finite measure preserving transformation, the notion was gradually genera…
What is Cost?
Damien Gaboriau
Two-page paper on the notion of cost of groups and measured equivalence relations to appear in the "What is?" series in the Notices of the AMS.
An Uncountable Family of Non Orbit Equivalent Actions of
Damien Gaboriau, Sorin Popa
For each , we construct an uncountable family of free ergodic measure preserving actions of the free group on the standard probability space…
