Zariski-Closures of Linear Reflection Groups

Jacques Audibert, Sami Douba, Gye-Seon Lee +1

We give necessary and sufficient conditions for a linear reflection group in the sense of Vinberg to be Zariski-dense in the ambient projective general linear group. As an applicat…

Zariski-dense Hitchin representations in uniform lattices

Jacques Audibert

We construct Zariski-dense surface subgroups in infinitely many commensurability classes of uniform lattices of the split real Lie groups $SL (n, R)$ , $\opera…

Zariski-dense surface groups in non-uniform lattices of split real Lie groups

Jacques Audibert

For $SL (n, R)$ ( $n \geq 3$ ), $SO (n + 1, n)$ ( $n \geq 2$ ), $Sp (2 n, R)$ ( $n \geq 2$ ) and for the adjoint real split form of the exceptional group $\…
