Time-periodic solutions in Einstein AdS - massless scalar field system

Maliborski, Maciej, Rostworowski, Andrzej

Understand

We construct time-periodic solutions for a system of self-gravitating massless scalar field, with negative cosmological constant, in d+1 spacetime dimensions at spherical symmetry, both perturbatively and numerically.

  • We estimate the convergence radius of the formally obtained perturbative series and argue that it is greater then zero.
  • Moreover, this estimate coincides with the boundary of the convergence domain of our numerical method and the threshold for the black-hole formation.
  • Then we confirm our results with a direct numerical evolution.
