报告摘要:
We present a simplified framework of numerical relativity in the characteristic formalism that can treat dynamical evolution, static solution and linear perturbation in a unified way. This framework is most suitable for asymptotically AdS black holes, but it can also be used in other kinds of gravitational systems. As an interesting example, we investigate the spontaneous breaking of the spherical symmetry in an AdS black hole system. The phase diagram of the static solutions, the linear stability analysis (quasi-normal modes) and the fully nonlinear dynamical simulation are all achieved in our simplified framework of numerical relativity.
