Time-periodic solutions of massive scalar fields in dynamical AdS background: Perturbative constructions

Time-periodic solutions of massive scalar fields in dynamical AdS background: Perturbative constructions

We consider scalar fields which are coupled to Einstein gravity with a negative cosmological constant, and construct periodic solutions perturbatively. In particular, we study tachyonic scalar fields whose mass is at or above the Breitenlohner–Freedman bound in four, five, and seven spacetime dimens...
