Group actions on dendrites and curves
B Duchesne, N Monod - Annales de l'Institut Fourier, 2018 - numdam.org
We establish obstructions for groups to act by homeomorphisms on dendrites. For instance,
lattices in higher rank simple Lie groups will always fix a point or a pair. The same holds for …

Invariantly universal analytic quasi-orders
R Camerlo, A Marcone, L Motto Ros - Transactions of the American …, 2013 - ams.org
We introduce the notion of an invariantly universal pair $(S, E) $ where $ S $ is an analytic
quasi-order and $ E\subseteq S $ is an analytic equivalence relation. This means that for …
