Abstract
We study gravitational perturbations around the near horizon geometry
of the (near) extreme Kerr black hole. By considering a consistent
truncation for the metric fluctuations, we obtain a solution to the
linearized Einstein equations. The dynamics is governed by two master
fields which, in the context of the nAdS_22/nCFT_11
correspondence, are both irrelevant operators of conformal dimension
\Delta=2Δ=2.
These fields control the departure from extremality by breaking the
conformal symmetry of the near horizon region. One of the master fields
is tied to large diffeomorphisms of the near horizon, with its equations
of motion compatible with a Schwarzian effective action. The other field
is essential for a consistent description of the geometry away from the
horizon.
