Titre Weak fields and effective integrability in AdS
Résumé I will start with a bit of general review of the AdS stability program exploring the elaborate nonlinear dynamics of small perturbations in Anti-de Sitter spacetime. The main mathematical tool for these investigations is nonlinear perturbation theory based on application of the time-averaging method. I will then focus on a specific simple realization of this setup (conformally coupled self-interacting probe scalar in AdS), for which the resulting effective time-averaged dynamics displays remarkable features connecting to the "cubic Szegő equation" (actively studied in the current math literature) and suggestive of integrability.
