Most Hitchin representations are strongly dense

D. D. Long, A. W. Reid, M. Wolff

We prove that generic Hitchin representations are strongly dense: every pair of non commuting elements in their image generate a Zariski-dense subgroup of SL_n(R). The proof uses a…

Deforming convex projective manifolds

Daryl Cooper, Darren Long, Stephan Tillmann

We study a properly convex real projective manifold with (possibly empty) compact, strictly convex boundary, and which consists of a compact part plus finitely many convex ends. We…

Constructing thin subgroups commensurable with the figure-eight knot group

Samuel A. Ballas, Darren Long

In this paper we find infinitely many lattices in each of which contains thin subgroups commensurable with the figure-eight knot group.

A generalization of the Epstein-Penner construction to projective manifolds

Daryl Cooper, Darren Long

We extend the canonical cell decomposition due to Epstein and Penner of a hyperbolic manifold with cusps to the strictly convex setting. It follows that a sufficiently small deform…

On Convex Projective Manifolds and Cusps

Daryl Cooper, Darren Long, Stephan Tillmann

This study of properly or strictly convex real projective manifolds introduces notions of parabolic, horosphere and cusp. Results include a Margulis lemma and in the strictly conve…

Commensurators of non-free finitely generated Kleinian groups

C. J. Leininger, D. D. Long, A. W. Reid

Suppose G is a non-free finitely generated Kleinian group without parabolics which is not a lattice and let C(G) denote the commensurator in PSL(2,C). We prove that if the limit se…
