DESCRIPTION:Using ambient space we develop a fully gauge and o
(d\,2) covariant approach to boundary values of Ad
S(d+1) gauge fields. It is applied to the study of
(partially) massless fields in the bulk and (high
er-order) conformal scalars\, i.e. singletons. We
prove the appropriate generalization of the Flato-
Fronsdal theorem on the decomposition of the tenso
r product of two singletons\, which is in agreemen
t with the known structure of symmetries for the h
igher-order wave operator. All these facts support
the following generalization of the higher-spin h
olographic duality: the O(N) model at an isotropic
Lifshitz point should be dual to the theory of pa
rtially massless symmetric tensor fields described
by the Vasiliev equations based on the higher-ord
er singleton symmetry algebra.
