Notes on a paper of Mess
These notes are a companion to the article "Lorentz spacetimes of constant
curvature" by Geoffrey Mess, which was first written in 1990 but never
published. Mess' paper will appear together with these notes in a forthcoming
issue of Geometriae Dedicata.Comment: 26 page
Realising end invariants by limits of minimally parabolic, geometrically finite groups
We shall show that for a given homeomorphism type and a set of end invariants
(including the parabolic locus) with necessary topological conditions which a
topologically tame Kleinian group with that homeomorphism type must satisfy,
there is an algebraic limit of minimally parabolic, geometrically finite
Kleinian groups which has exactly that homeomorphism type and end invariants.
This shows that the Bers-Sullivan-Thurston density conjecture follows from
Marden's conjecture proved by Agol, Calegari-Gabai combined with Thurston's
uniformisation theorem and the ending lamination conjecture proved by Minsky,
partially collaborating with Masur, Brock and Canary.Comment: fourth version: Introduction rewritten; some arguments in Sec. 5 and
6 clarified
