Schottky presentations of positive representations
Jean-Philippe Burelle, Nicolaus Treib
We show that the notion of -hyperconvexity on oriented flag manifolds defines a partial cyclic order. Using the notion of interval given by this partial cyclic order, we constru…

Domains of discontinuity in oriented flag manifolds
Florian Stecker, Nicolaus Treib
We study actions of discrete subgroups of semi-simple Lie groups on associated oriented flag manifolds. These are quotients , where the subgroup lies between a par…
