Most general theory of 3d gravity: Covariant phase space, dual diffeomorphisms, and more
Marc Geiller, Christophe Goeller, Nelson Merino
We show that the phase space of three-dimensional gravity contains two layers of dualities: between diffeomorphisms and a notion of "dual diffeomorphisms" on the one hand, and betw…
First-order Lagrangian and Hamiltonian of Lovelock gravity
Pablo Guilleminot, Félix-Louis Julié, Nelson Merino +1
Based on the insight gained by many authors over the years on the structure of the Einstein-Hilbert, Gauss-Bonnet and Lovelock gravity Lagrangians, we show how to derive -- in an e…
Mimetic Einstein-Cartan-Kibble-Sciama (ECKS) gravity
F. Izaurieta, P. Medina, N. Merino +2
In this paper, we formulate the Mimetic theory of gravity in first-order formalism for differential forms, i.e., the mimetic version of Einstein-Cartan-Kibble-Sciama (ECKS) gravity…
Semi-simple enlargement of the algebra from a Chern-Simons theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez +2
In this work we present a BMS-like ansatz for a Chern-Simons theory based on the semi-simple enlargement of the Poincaré symmetry, also known as AdS-Lorentz algebra. We start by sh…
Asymptotic symmetries of three-dimensional Chern-Simons gravity for the Maxwell algebra
Patrick Concha, Nelson Merino, Olivera Miskovic +3
We study a three-dimensional Chern-Simons gravity theory based on the Maxwell algebra. We find that the boundary dynamics is described by an enlargement and deformation of the $\ma…
Chern-Weil theorem, Lovelock Lagrangians in critical dimensions and boundary terms in gravity actions
Nathalie Deruelle, Nelson Merino, Rodrigo Olea
In this paper we show how to translate into tensorial language the Chern-Weil theorem for the Lorentz symmetry, which equates the difference of the Euler densities of two manifolds…
