We derive the propagators for higherspin master fields in antide Sitter space of arbitrary dimension. A method is developed to construct the propagators directly without solving any differential equations. The use of the ambient space, where AdS is represented as a hyperboloid and its conformal boundary as a projective lightcone, simplifies the approach and makes a direct contact between boundarytobulk propagators and twopoint functions of conserved currents.

We study asymptotically Lifshitz solutions to three dimensional higher spin gravity in the SL(3,R)×SL(3,R) ChernSimons formulation. We begin by specifying the most general connections satisfying Lifshitz boundary conditions, and we verify that their algebra of symmetries contains a Lifshitz subalgebra. We then exhibit connections that can be viewed as higher spin Lifshitz black holes. We show that when suitable holonomy conditions are imposed, these black holes obey sensible thermodynamics and possess a gauge in which the corresponding metric exhibits a regular horizon. ar X iv

We study deformations of threedimensional large N CFTs by doubletrace operators constructed from spin s singletrace operators of dimension ∆. These theories possess UV fixed points, and we calculate the change of the 3sphere free energy δF = FUV − FIR. To describe the UV fixed point using the dual AdS4 space we modify the boundary conditions on the spin s field in the bulk; this approach produces δF in agreement with the field theory calculations. If the spin s operator is a conserved current, then the fixed point is described by an induced parity invariant conformal spin s gauge theory. The low spin examples are QED3 (s = 1) and the 3d induced conformal gravity (s = 2). When the original CFT is that of N conformal complex scalar or fermion fields, the U(N) singlet sector of the induced 3d gauge theory is dual to Vasiliev’s theory in AdS4 with alternate boundary conditions on the spin s massless gauge field. We test this correspondence by calculating the leading term in δF for large N. We show that the coefficient of 1 2 logN in δF is equal to the number of spin s − 1 gauge parameters that act trivially on the spin s gauge field. We discuss generalizations of these results to 3d gauge theories including ChernSimons terms and to theories where s is halfinteger. We also argue that the Weyl anomaly acoefficients of conformal spin s theories in even dimensions d, such as that of the Weylsquared gravity in d = 4, can be efficiently calculated using massless spin s fields in AdSd+1 with alternate boundary conditions. Using this method we derive a simple formula for the Weyl anomaly acoefficients of the d = 4 FradkinTseytlin conformal higherspin gauge fields. Similarly, using alternate boundary conditions in AdS3 we reproduce the wellknown central charge c = −26 of the bc ghosts in 2d gravity, as well as its higherspin generalizations.
