Arick Shao | Bulk-boundary correspondence for vacuum asymptotically Anti-de Sitter spacetimes

3/21/2022 CMSA General Relativity Seminar Speaker: Arick Shao (Queen Mary University of London) Title: Bulk-boundary correspondence for vacuum asymptotically Anti-de Sitter spacetimes Abstract: The AdS/CFT conjecture in physics posits the existence of a correspondence between gravitational theories in asymptotically Anti-de Sitter (aAdS) spacetimes and field theories on their conformal boundary. In this presentation, we prove rigorous mathematical statements toward this conjecture. In particular, we show there is a one-to-one correspondence between aAdS solutions of the Einstein-vacuum equations and a suitable space of data on the conformal boundary (consisting of the boundary metric and the boundary stress-energy tensor). We also discuss consequences of this result, as well as the main ingredient behind its proof: a unique continuation property for wave equations on aAdS spacetimes. This is joint work with Gustav Holzegel (and makes use of joint works with Alex McGill and Athanasios Chatzikaleas).
