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.

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.

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

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 PhysicsIn 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 BThe 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 PhysicsWe 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.

Higher spin de Sitter quantum gravity [PDF]
Journal of High Energy Physics, 2015 We consider Einstein gravity with positive cosmological constant coupled with higher spin interactions and calculate Euclidean path integral perturbatively. We confine ourselves to the static patch of the 3 dimensional de Sitter space. This geometry, when Euclideanlized is equivalent to 3-sphere.
