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.

Towards higher-spin AdS2/CFT1 holography

Journal of High Energy Physics, 2020
We aim at formulating a higher-spin gravity theory around AdS2 relevant for holography. As a first step, we investigate its kinematics by identifying the low-dimensional cousins of the standard higher-dimensional structures in higher-spin gravity such as

Planar solutions of higher-spin theory. Nonlinear corrections

Journal of High Energy Physics, 2022
Leading order higher-spin corrections to the linearized higher-spin black brane are analyzed in four dimensions. It is shown that the static solution that respects planar symmetry exists in the bosonic case at given order.

Higher-spin initial data in twistor space with complex stargenvalues

Journal of High Energy Physics, 2020
This paper is a supplement to and extension of arXiv:1903.01399. In the internal twistor space of the 4D Vasiliev’s higher-spin gravity, we study the star-product eigenfunctions of number operators with generic complex eigenvalues.

Metaplectic representation and ordering (in)dependence in Vasiliev’s higher spin gravity

Journal of High Energy Physics, 2022
We investigate the formulation of Vasiliev’s four-dimensional higher-spin gravity in operator form, without making reference to one specific ordering.

Differential contracting homotopy in higher-spin theory

Journal of High Energy Physics, 2023
A new efficient approach to the analysis of nonlinear higher-spin equations, that treats democratically auxiliary spinor variables Z A and integration homotopy parameters in the non-linear vertices of the higher-spin theory, is developed.

On the local frame in nonlinear higher-spin equations

Journal of High Energy Physics, 2018
Properties of the resolution operator dloc∗ in higher-spin equations, that leads to local current interactions at the cubic order and minimally nonlocal higher-order corrections, are formulated in terms of the condition on the class of master fields of ...

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
