Superrigidity for representations of transverse measured groupoids

Filippo Sarti, Alessio Savini

For $i = 1, \dots, k$ , let $G_{i}$ be a connected, simply connected, semisimple algebraic group over some local field $κ_{i}$ of characteristic zero. Let $G_{i} = G_{i} (κ_{i})$ …

Bounded cohomological induction for transverse measured groupoids

Tobias Hartnick, Filippo Sarti

We establish an induction isomorphism in the context of measurable bounded cohomology of discrete measured groupoid, which generalizes the Eckmann-Shapiro isomorphism in bounded co…

Simplicial volume via foliated simplices and duality

Filippo Sarti

Let $M$ be a triangulated oriented closed connected manifold with universal cover $M \to M$ and fundamental group $Γ = π_{1} (M)$ and consider an essentially free measure pre…
