Unitarity Bounds in AdS_3 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.

On the spectrum of pure higher spin gravity [PDF]
Journal of High Energy Physics, 2020 We study the spectrum of pure massless higher spin theories in AdS3. The light spectrum is given by a tower of massless particles of spin s = 2, ⋯ , N and their multi-particles states. Their contribution to the torus partition function organises into the

Classical Aspects of Higher Spin Topologically Massive Gravity [PDF]
Classical and Quantum Gravity, 2012 We study the classical solutions of three dimensional topologically massive gravity (TMG) and its higher spin generalization, in the first order formulation.

Black holes in Truncated Higher Spin AdS$_3$ Gravity [PDF]
Journal of High Energy Physics, 2012 We study the higher spin black holes in a truncated version of higher spin gravity in $AdS_3$. This theory contains only finite number of even spins s=2,4,...,2N.

How higher-spin gravity surpasses the spin two barrier: no-go theorems versus yes-go examples [PDF]
Reviews of Modern Physics, 2012 Aiming at non-experts, we explain the key mechanisms of higher-spin extensions of ordinary gravity. We first overview various no-go theorems for low-energy scattering of massless particles in flat spacetime.

Boundary freedom in higher spin gravity
Physics Letters BWe investigate new boundary conditions in three-dimensional asymptotically Anti–de Sitter gravity coupled to higher-spin fields, allowing for arbitrary boundary degrees of freedom.

More on Chiral Higher Spin Gravity and convex geometry [PDF]
Nuclear Physics B, 2022 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.

Geometric tool kit for higher spin gravity (part I): An introduction to the geometry of differential operators [PDF]
International Journal of Modern Physics A, 2023 These notes provide an introduction to the algebra and geometry of differential operators and jet bundles. Their point of view is guided by the leitmotiv that higher-spin gravity theories call for higher-order generalisations of Lie derivatives and ...

Asymptotic dynamics of three dimensional supergravity and higher spin gravity revisited [PDF]
Journal of High Energy Physics, 2023 We reconsider the Hamiltonian reduction of the action for three dimensional AdS supergravity and W3 higher spin AdS gravity in the Chern-Simons formulation under asymptotically anti-de Sitter boundary conditions.

Geometric tool kit for higher spin gravity (part II): An introduction to Lie algebroids and their enveloping algebras [PDF]
International Journal of Modern Physics A, 2023 These notes provide a self-contained introduction to Lie algebroids, Lie-Rinehart algebras and their universal envelopes. This review is motivated by the speculation that higher-spin gauge symmetries should admit a natural formulation as enveloping ...
