Some open questions on anti-de Sitter geometry
arXiv:1205.6103
Abstract
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 homogeneous spaces and discrete subgroups of Lie groups, to Teichmüller theory, as well as analogs in hyperbolic geometry.
Not a research article in the usual sense but rather a list of open questions. 19 pages
