Description
Consider any asymptotically AdS spacetime. We introduce a
special class of spacelike cross-sections of the boundary
called light-cone cuts. We will first show that the
conformal metric in the bulk (i.e. the metric up to an
overall conformal factor) can be reconstructed just from the
location of these cuts. We then show how the light-cone cuts
can be determined from the dual field theory. Finally we
show how (at least in some cases) the conformal factor can
also be determined. This provides a new approach to
determining the bulk geometry from the dual field theory.
These results were obtained in collaboration with Netta
Engelhardt.
