Interactions in higher-spin gravity: a holographic perspective [PDF]

Journal of Physics A: Mathematical and Theoretical, 2017
This thesis is an elaboration of recent results on the holographic re-construction of metric-like interactions in higher-spin gauge theories on anti-de Sitter space (AdS), employing their conjectured holographic duality with free conformal field theories (CFTs).

Towards higher-spin holography in flat space

Journal of High Energy Physics, 2023
We study the chiral flat space higher-spin algebra, which is the global symmetry algebra of the chiral higher-spin theory in the 4d Minkowski space. We find that it can be constructed as the universal enveloping algebra of a certain chiral deformation of

On resolutions of cosmological singularities in higher-spin gravity [PDF]

International Journal of Modern Physics D, 2019
We study the resolution of certain cosmological singularity in the context of higher-spin three-dimensional gravity. We consider gravity coupled to a spin-3 field realized as Chern–Simons theory with gauge group [Formula: see text]. In this context, we elaborate and extend a singularity resolution scheme proposed by Krishnan and Roy.

Chiral higher-spin holography in flat space: the Flato-Fronsdal theorem and lower-point functions

Journal of High Energy Physics, 2023
We prove the flat space analogue of the Flato-Fronsdal theorem. It features the flat space singleton representation suggested recently. We do that by deriving a kernel that intertwines a pair of singleton representations with massless higher-spin fields ...

Higher-spin gravity in two dimensions with vanishing cosmological constant

Journal of High Energy Physics
In this paper, we use a version of the BF formulation of two-dimensional dilaton gravity that allows to define a gauge theory of the two-dimensional Poincaré or Maxwell algebras and several of their higher-spin generalisations, both of finite and ...

Topological fields in 4d higher spin theory

Physics Letters B
The equations for topological fields in the 4d higher spin theory are considered. It is shown that these fields contain a finite number of degrees of freedom that justifies their naming.

Chiral higher-spin double copy

Journal of High Energy Physics
We construct the double copy of the chiral higher-spin theory. It is a Lorentz invariant theory with the little group spectrum given by the tensor square of the chiral higher-spin theory spectrum.

More on Chiral Higher Spin Gravity and convex geometry

Nuclear Physics B, 2023
Recently, a unique class of local Higher Spin Gravities with propagating massless fields in $4d$ - Chiral Higher Spin Gravity - was given a covariant formulation both in flat and $(A)dS_4$ spacetimes at the level of equations of motion. We unfold the corresponding homological perturbation theory as to explicitly obtain all interaction vertices.
