Crooked Halfspaces
Jean-Philippe Burelle, Virginie Charette, Todd Drumm +1
We develop the Lorentzian geometry of a crooked halfspace in 2+1-dimensional Minkowski space. We calculate the affine, conformal and isometric automorphism groups of a crooked half…
A 3-Manifold with no Real Projective Structure
Daryl Cooper, William Goldman
We show that the connected sum of two copies of real projective 3-space does not admit a real projective structure. This is the first known example of a connected 3-manifold withou…
Some open questions on anti-de Sitter geometry
Thierry Barbot, Francesco Bonsante, Jeffrey Danciger +6
We present a list of open questions on various aspects of AdS geometry, that is, the geometry of Lorentz spaces of constant curvature -1. When possible we point out relations with…
Topological tameness of Margulis spacetimes
Suhyoung Choi, William Goldman
We show that Margulis spacetimes without parabolic holonomy are topologically tame. A Margulis spacetime is the quotient of the -dimensional Minkowski space by a free proper iso…
