The gravitational collapse of a minimally coupled scalar field in (d + 1)-dimensional Anti-de Sitter spacetime is examined via a collection of manuscripts that are, or are in the process of, being published. First, the results of the numerical evolution of the 5-dimensional nonlinear Einstein equations are used to construct a phase diagram of collapse behaviours, taking the mass and width of the initial profile as parameters. Next, we test the limits of a family of perturbative solutions for massless scalars with static boundary conditions in AdS%u2084. Finally, we derive set of flow equations for the time evolution of a massive scalar field in the perturbative description of AdS%u2084 with time-dependent boundary conditions.
