Cosmological shapes of higher-spin gravity [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 We explore non-Gaussian features of a massless spin-two field in the Vasiliev theory of higher-spin gravity. The theory contains an infinite tower of interacting gauge fields with increasing spin, and admits four-dimensional asymptotically de Sitter configurations.

Thermofield duality for higher spin Rindler Gravity [PDF]
Journal of High Energy Physics, 2016 We study the Thermo-field realization of the duality between the Rindler-AdS higher spin theory and $O(N)$ vector theory. The CFT represents a decoupled pair of free $O(N)$ vector field theories. It is shown how this decoupled domain CFT is capable of generating the connected Rindler-AdS background with the full set of Higher Spin fields.

Nuclear Physics B, 2019 We present a complete solution to the problem of Formal Higher Spin Gravities --- formally consistent field equations that gauge a given higher spin algebra and describe free higher spin fields upon linearization. The problem is shown to be equivalent to constructing a certain deformation of the higher spin algebra as an associative algebra. Given this

Unfolded Fierz-Pauli equations in three-dimensional asymptotically flat spacetimes
Journal of High Energy Physics, 2023 We utilise a quotient of the universal enveloping algebra of the Poincaré algebra in three spacetime dimensions, on which we formulate a covariant constancy condition.

Chiral higher spin gravity and convex geometry
SciPost Physics, 2023 Chiral Higher Spin Gravity is the minimal extension of the graviton with propagating massless higher spin fields. It admits any value of the cosmological constant, including zero. Its existence implies that Chern-Simons vector models have closed subsectors and supports the

Twisted Flato-Fronsdal theorem for higher-spin algebras
Journal of High Energy Physics, 2018 We explore the relation between the singleton and adjoint modules of higher-spin algebras via so(2, d) characters. In order to relate the tensor product of the singleton and its dual to the adjoint module, we consider a heuristic formula involving ...

On z-dominance, shift symmetry and spin locality in higher-spin theory
Journal of High Energy Physics, 2023 The paper aims at the qualitative criterion of higher-spin locality. Perturbative analysis of the Vasiliev equations gives rise to the so-called z-dominated non-localities which nevertheless disappear from interaction vertices leaving the final result ...

Off-shell higher-spin fields in AdS 4 and external currents
Journal of High Energy Physics, 2021 We construct an unfolded system for off-shell fields of arbitrary integer spin in 4d anti-de Sitter space. To this end we couple an on-shell system, encoding Fronsdal equations, to external Fronsdal currents for which we find an unfolded formulation.
