Equicontinuous actions of semisimple groups
Uri Bader, Tsachik Gelander
We study equicontinuous actions of semisimple groups and some generalizations. We prove that any such action is universally closed, and in particular proper. We derive various appl…
Convergence groups are not invariably generated
Tsachik Gelander
It was conjectured in [KLS14] that non-elementary word hyperbolic groups are never invariably generated. We show that this is indeed the case even for the much larger class of conv…
Invariant random subgroups of linear groups
Tsachik Gelander, Yair Glasner
Let be a countable non-amenable linear group with a simple, center free Zariski closure, the space of all subgroups of with the, compact…
Lectures on Lattices and locally symmetric spaces
Tsachik Gelander
The aim of this short lecture series is to expose the students to the beautiful theory of lattices by, on one hand, demonstrating various basic ideas that appear in this theory and…
