講演内容
Anti-de Sitter (AdS) spacetime has been in the center of attention of the mathematical high-energy physics and gravity community over the last 20 years. It is both mathematically special (being a maximally symmetric spacetime) and related, via the conjectured AdS/CFT correspondence, to important questions of quantum field theories.
Anti-de Sitter spacetime is known to be linearly stable, but the perfectly resonant frequency spectrum of its linearized perturbations makes it very prone to nonlinear instabilities. I'll give an informal review of the research on weakly nonlinear dynamics of small AdS perturbations, and related systems, over the course of the recent years.
