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…

Dehn filling and the geometry of unknotting tunnels
Daryl Cooper, David Futer, Jessica S. Purcell
Any one-cusped hyperbolic manifold M with an unknotting tunnel tau is obtained by Dehn filling a cusp of a two-cusped hyperbolic manifold. In the case where M is obtained by "gener…

Non-faithful representations of surface groups into SL(2,C) which kill no simple closed curve
Daryl Cooper, Jason Fox Manning
We give counterexamples to a version of the simple loop conjecture in which the target group is PSL(2,C). These examples answer a question of Minsky in the negative.
