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 ...

Minimal models of field theories: Chiral higher spin gravity [PDF]
, 2022 peer reviewedThere exists a unique class of local higher spin gravities with propagating massless fields in 4d - chiral higher spin gravity. Originally, it was formulated in the light-cone gauge.

Unitarity bounds in AdS3 higher spin gravity [PDF]
Journal of High Energy Physics, 2012 We study SL(N,R) Chern-Simons gauge theories in three dimensions. The choice of the embedding of SL(2,R) in SL(N,R), together with asymptotic boundary conditions, defines a theory of higher spin gravity. Each inequivalent embedding leads to a different asymptotic symmetry group, which we map to an OPE structure at the boundary.

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.
