  The behavior of the divergent part of the bulk AdS/CFT effective action is
considered with respect to the special finite diffeomorphism transformations
acting on the boundary as a Weyl transformation of the boundary metric. The
resulting 1-cocycle of the Weyl group is in full agreement with the 1-cocycle
of the Weyl group obtained from the cohomological consideration of the
effective action of the corresponding CFT.
