Cross ratios and cubulations of hyperbolic groups
Jonas Beyrer, Elia Fioravanti
Many geometric structures associated to surface groups can be encoded in terms of invariant cross ratios on their circle at infinity; examples include points of Teichmüller space,…

cube complexes are determined by their boundary cross ratio
Jonas Beyrer, Elia Fioravanti, Merlin Incerti-Medici
We introduce a -valued cross ratio on Roller boundaries of cube complexes. We motivate its relevance by showing that every cross-ratio preserving bijecti…
