Quantizing higher-spin gravity in free-field variables

We study the formulation of massless higher-spin gravity on AdS3 in a gauge in which the fundamental variables satisfy free field Poisson brackets. This gauge choice leaves a small portion of the gauge freedom unfi...

Weyl gravity in covariant hamiltonian formalism

We find covariant canonical formalism for Weyl invariant gravity. We discuss constraint structure of this theory and its gauge fixed form and we argue that it corresponds to unimodular gravity....

Hamiltonian for Weyl transverse gravity

In this short note we determine Hamiltonian for Weyl transverse gravity. We find primary, secondary and tertiary constraints and calculate Poisson brackets between them. We also show that gauge fixing in Weyl transverse gravity<...

A first-order approach to conformal gravity

We investigate whether a spontaneously-broken gauge theory of the group SU(2, 2 of the theory are an SU(2, 2) gauge field Aμ and a Higgs field W in the adjoint(1, 3) -> SO(1, 1). The action for gravity is polynomial in {Aμ,...

The Newman-Penrose map and the classical double copy

Gauge-gravity duality is arguably our best hope for understanding quantum gravity. Considerable progress has been made in relating scattering amplitudes in certain gravity theories to those in gauge theori...

Compatibility complex for black hole spacetimes

The set of local gauge invariant quantities for linearized gravity on the Kerr:051104, 2018) is shown to be complete. In particular, any gauge invariant quantity for linearized gravity on Kerr that is local and of ...

Presymplectic AKSZ formulation of Einstein gravity

Any local gauge theory can be represented as an AKSZ sigma model (upon parameterization if necessary). However, for non-topological models in dimension higher than 1. This leads to a very concise AKSZ-like representation for frame-like Lagra...

Two-dimensional f(R) Horava-Lifshitz gravity

We study two-dimensional f (R)Horava-Lifshitz gravity from the Hamiltonian point of view. We determine constraints structure with emphasis on the careful separation of the second class constraints and global first class constraints. We deter...

Double-copying self-dual Yang-Mills theory to self-dual gravity on twistor space

and suggests a generalisation to gauged maximally supersymmetric self-dual gravity.We construct a simple Lorentz-invariant action for maximally supersymmetric self-dual Yang-Mills theory that manifests colour-kinematics duality. We...
