Bulk-Boundary Correspondences and Unique Continuation in Asymptotically Anti-de Sitter Spacetimes

This article surveys the research presented by the author at the MATRIX Institute workshop Hyperbolic Differential Equations in Geometry and Physics in April 2022. The work is centred about establishing rigorous mathematical statements toward the AdS/CFT correspondence in theoretical physics, in particular in dynamical settings. The contents are mainly based on the recent paper [37] with Gustav Holzegel that proved a unique continuation result for the Einstein-vacuum equations from asymptotically Anti-de Sitter (aAdS) conformal boundaries. We also discuss some preceding results [20, 35, 36, 55, 59], in particular novel Carleman estimates for wave equations on aAdS spacetimes, which laid the foundations toward the main results of [37].
