Description
I will discuss algebraically special solutions of four-dimensional gravity in the context of holography. These are exact solutions of the field equations that contain a number of arbitrary transverse functions subject to non-linear constraints. In the case of negative cosmological constant, the configuration space defined by such solutions is not compatible with standard Dirichlet boundary conditions, resulting in a modified holographic dictionary. I will discuss the variational problem for algebraically special solutions, its holographic interpretation, and its connection with the thermodynamics of accelerating AdS black holes.
