Generalized Cusps in Real Projective Manifolds: Classification

Samuel A. Ballas, Daryl Cooper, Arielle Leitner

A generalized cusp $C$ is diffeomorphic to $[0, \infty)$ times a closed Euclidean manifold. Geometrically $C$ is the quotient of a properly convex domain by a lattice, $Γ$ , in one o…

Rank 1 deformations of non-cocompact hyperbolic lattices

Samuel A. Ballas, Julien Paupert, Pierre Will

Let $X$ be a negatively curved symmetric space and $Γ$ a non-cocompact lattice in $Isom (X)$ . We show that small, parabolic-preserving deformations of $Γ$ into the isometry gro…
