On some aspects of discrete groups acting ergodically on the boundary

Subhadip Dey, Mikołaj Frączyk, Sebastian Hurtado

We show that if $G$ is a real semisimple Lie group and $Γ < G$ is a discrete subgroup with slow growth, in the sense that its growth indicator function is smaller than $ρ$ , then $Γ$ …

Infinitesimal containment and sparse factors of iid

Mikołaj Frączyk

We introduce infinitesimal weak containment for measure-preserving actions of a countable group $Γ$ : an action $(X, μ)$ is infinitesimally contained in $(Y, ν)$ if the statistics of…

Discrete subgroups with finite Bowen-Margulis-Sullivan measure in higher rank

Mikolaj Fraczyk, Minju Lee

Let $G$ be a connected semisimple real algebraic group and $Γ < G$ be its Zariski dense discrete subgroup. We prove that if $Γ\ G$ admits any finite Bowen-Margulis-Sullivan…
