Rigidity of anti-de Sitter (2+1)-spacetimes with convex boundary near the Fuchsian locus
arXiv:2502.01599
Abstract
We prove that globally hyperbolic compact anti-de Sitter (2+1)-spacetimes with strictly convex spacelike boundary that is either smooth or polyhedral and whose holonomy is close to Fuchsian are determined by the induced metric on the boundary.
