Description
In gravitational theories involving higher curvature
corrections the metric describes additional degrees of
freedom beyond the graviton. Holographic duality maps these
to operators in the dual CFT. We identify infinite families
of theories for which these new modes cannot be truncated
and the usual Fefferman-Graham expansion needs to be
modified. New massive gravity in three dimensions and
critical gravity in four dimensions are particular
representatives of these families. We propose modified
expansion, study the near-boundary behaviour of the metric
and derive fall-off properties of the additional modes in
theories involving higher derivative corrections. Based on
