Thin shell dynamics in Lovelock gravity
Pablo Guilleminot, Nelson Merino, Rodrigo Olea
We study matching conditions for a spherically symmetric thin shell in Lovelock gravity which can be read off from the variation of the corresponding first-order action. In point o…
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…
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…
Einstein-Gauss-Bonnet theory of gravity: The Gauss-Bonnet-Katz boundary term
Nathalie Deruelle, Nelson Merino, Rodrigo Olea
We propose a boundary term to the Einstein-Gauss-Bonnet action for gravity, which is constructed as the dimensional continuation of the Chern-Weil theorem, and such that the extrem…
