Convex projective manifolds, symmetric spaces and geometric decompositions
Stefano Riolo, Andrea Seppi, Leone Slavich
The authors show that any closed, indecomposable, properly convex real projective 4‑manifold that is geometric or admits a Thurston‑type geometric decomposition must consist of rea…

Subspace stabilisers in hyperbolic lattices
Mikhail Belolipetsky, Nikolay Bogachev, Alexander Kolpakov +1
This paper shows that immersed totally geodesic -dimensional suborbifolds of -dimensional arithmetic hyperbolic orbifolds correspond to finite subgroups of the commensurator…
